VITRIMERS:

Vitrimers is a relatively new term for a class of polymers that have existed for decades. These classes of polymers are special as they have properties of both thermosets and thermoplastics. Traditionally, thermoplastics can be recycled and reworked. Thermosets are generally known to not undergo any further reactions and chemical changes once they are formed and crosslinked.

Vitrimers have crosslinked structures like thermosets but they can be recycled like thermoplastics. This is made possible because of bond exchange reactions. These bond exchange reactions happen even in the solid state so the thermoset polymer has a mechanism of plasticity and adhesive bonding even in the solid-state.

The first vitrimer polymer was developed by James Economy’s group at UIUC in the 1990’s.The research demonstrated a new class of thermoset polymer systems that were processable by virtue of topology changes within the covalent networks as mediated by bond exchange reactions.This class of polymers was called aromatic thermosetting copolyester. It was shown composite laminae could be consolidated to make a dense composite structure.The Economy group conducted studies employing secondary ion mass spectrometry (SIMS) on deuterated and nondeuterated fully cured vitrimer layers to discriminate the length scales (<50 nm) for physical interdiffusion between vitrimers constituent atoms providing evidence towards eliminating physical interdiffusion of the polymer chains as the governing mechanism for bonding between vitrimer layers.

The term vitrimer came after two decades of this work and it has drawn interest to this new field of polymers.Vitrimers were first termed as such in the early 2010s by French researcher Ludwik Leibler, from CNRS. Leibler and co-workers developed silica-like networks using the wellestablished transesterification reaction of epoxy and fatty dicarboxylic or tricarboxylic acids. Besides epoxy resins, other polymer networks have been used to produce vitrimers, such as aromatic polyesters, polylactic acid (polylactide),polyhydroxyurethanes,epoxidized soybean oil with citric acid and polybutadiene.

Healthcare:

The integration of Smart materials is transforming the healthcare industry by addressing long-standing challenges. Consider the possibilities of prosthetic limbs that dynamically adjust their shape to match various objects,providing amputees with a natural and adaptive grip. With the strategic incorporation of vitrimers, prosthetic technologies are advancing, enabling wearers to regain functionality and enhance their quality of life.

Smart plastics are driving innovation in the development of smart bandages that intelligently adapt to changes in wound conditions.These bandages leverage their shapeshifting properties to optimize healing and prevent infections by releasing targeted medications/adjusting their shape to suit the wound environment.

Svante August Arrhenius-Nobel Prize 1903

This Swedish physical chemist is best known for his theory of electrolytic dissociation in aqueous solution, first presented for his doctorate thesis at the University of Uppsala when he was 24. The idea that oppositely charged ions resulting from dissociation of molecules could be present in the same solution initially met a hostile reception, but with support from Ostwald, van't Hoff and others the theory was gradually accepted.

Arrhenius was able to demonstrate the effect of electrolytic dissociation on osmotic pressure, lowering the freezing point, and increasing the boiling point of solutions containing electrolytes.

He then examined the relationship between toxins and antitoxins, their importance in relation to biological problems such as serum therapy, digestion and absorption, as well as gastric and pancreatic juices. The great importance of electrolytic dissociation theory is universally accepted today, even if some modifications have been found necessary.

Arrhenius also applied physicochemical principles to the study of meteorology, cosmology, and biochemistry. In meteorology, he predicted the scientific conclusion that increased concentrations of greenhouse gases in the atmosphere cause global warming.

Svante Arrhenius made important contributions to our understanding of the greenhouse effect and the role of greenhouse gases in Earth’s climate. In 1896, he published an article entitled “On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground,”which suggested that the increase in carbon dioxide in the atmosphere caused by human activities could lead to global warming.

Arrhenius suggested that the carbon dioxide, water vapor and other gases in the Earth’s atmosphere acted like a greenhouse by trapping heat from the sun and preventing it from escaping back into space. He calculated that doubling the concentration of carbon dioxide in the atmosphere could raise global temperatures by up to 5-6 degrees Celsius.

He is also known for the Arrhenius Equation k = A exp -E/RT, which describes the effect of temperature on reaction rates. He was instrumental in establishing physical chemistry as a separate discipline. A man of eclectic scientific interests, he later published papers on immunology, cosmology and geology. He was awarded the 1903 Nobel Prize in Chemistry.

Asahi Kasei presents diversified material solutions for EV batteries and circular economy

Japanese technology company Asahi Kasei will showcase diversified material solutions for safe and compact EV batteries, improved connectivity and lightweighting, as well as circular economy at Fakuma, an event for industrial plastics processing, from 17 – 21 October 2023 in Frie-drichshafen, Germany.     

Thermoplastic composites for EV battery applications:

This year, Asahi Kasei will put a special focus on its broad range of materials for lightweight, compact, and safe electric vehicle battery solutions. The company is currently developing a new continuous glass fiber reinforced thermoplastic, LENCEN™, and will present it for the first time at the European trade show #Fakuma. This composite material is formed by stacking layers of continuous glass fiber textiles with #polyamide66 (PA66) films. Due to its tensile strength, high heat resistance, and impact properties similar to metal, this material improves collision safety and weight reduction of EV batteries.

In addition, the company will showcase a carbon fiber reinforced thermoplastic unidirectional tape (CFRTP-UD tape) that utilizes both recycled continuous carbon fiber and the company’s LEONA™ polyamide resin. Boasting a higher strength than metal, this CFRTP-UD tape can be applied to automobile frames and bodies, further enabling the recycling of end-of-vehicle-life parts into different, new automobile parts.

Asahi Kasei will also showcase #coolingpipes for #EVbattery packs made of the modified #polyphenyleneether (m-PPE) XYRON™, as well as 2170 cell trays based on the m-PPE particle foam SunForce™.

Solutions for improved HMI and glass replacement

AZP™ is a #transparent polymer that overcomes the disadvantages of conventional optical plastic materials. Featuring a close-to-zero #birefringence equivalent to glass as well as a superior designability, this material allows high transmittance and low color distortions at all viewing angles. Clear images without luminance variations, color distortion and blurring can be achieved in polarized optical equipment such as AR/VR headsets and head-up-displays (HUDs). The premium quality appearance is also maintained when looking at the display through polarized #sunglasses.

Bio-based feedstock and new recycling technology for PA66

#AsahiKasei will display a #biobased and #biodegradable #cellulosenanofiber (CNF). This material is made from #cotton linter and features a high heat resistance and network-forming ability. CNF-reinforced polyamide shows a thixotropic behavior, making it highly suitable for #3dprinting applications in terms of easy printing, dimensional accuracy, smooth appearance, and mechanical performance. Furthermore, CNF has superior material recyclability compared to glass fibers.

Cleaning the equipment after processing the plastics in an efficient and cost-effective manner is a major challenge for many companies. Asaclean™ is the worldwide leader in commercial purging compounds. Asaclean™ purges are optimized for injection molding, extrusion, film and sheet, blow-molding, and blown-film applications. Its benefits include faster changeovers/reduced downtime, effective removal of color/carbon contamination, reduced screw-pulls, lower scrap/reject rate, increased productivity, and greater cost savings.

The company will also present its comprehensive solutions for establishing a sustainable life cycle for PA66 utilizing bio-based feedstock and a new technology for chemical recycling. Together with Japanese partner company Microwave Chemical, the company is working on a new technology for chemical recycling of PA66. The process utilizes microwaves to depolymerize automotive airbags and
other PA66 parts and directly obtain the monomers hexamethylenediamine (HMD) and adipic acid (ADA), which is expected to be accomplished at high yield with low energy consumption. The monomers obtained can then be used to manufacture new PA66.

Today's KNOWLEDGE Share:Global Emissions

Today's KNOWLEDGE Share

The global energy crisis fueled fears of runaway growth in the world’s CO2 emissions – but new IEA analysis shows emissions rose by less than 1% in 2022 as a surge in clean energy offset most of the increase in emissions from coal & oil.

The rise in global CO2 emissions in 2022 would have been nearly 3 times as high if it wasn't for the strong growth of solar, wind, EVs, heat pumps & energy efficiency. Together, they prevented 550 million tonnes of emissions.

CO2 emissions from coal grew by 1.6% in 2022, more than offsetting the decline in emissions from natural gas amid the energy crisis. Oil's emissions were up 2.5%, a sharper rise than coal's, mainly driven by the rebound in air travel. But they still remain below their 2019 high.

While rising emissions from fossil fuels undermine efforts to meet the world’s climate goals, many fossil fuel companies made record profits in 2022. Given their public pledges, it’s vital that they review their strategies to ensure they’re aligned with real emissions reductions.

The new @International Energy Agency report on CO2 emissions in 2022 is the first in our new series on the Global Energy Transitions Stocktake, which brings our latest analysis together in one place to support the first Global Stocktake in the lead-up to #COP28.
