Polyurethane Composition with Enhanced Thermocompression Characteristics
Unmet Need: Challenges recycling and reprocessing polyurethane foams due to their thermoset behaviors Polyurethane foams are thermosets and accordingly, at their useful end of life, it may be challenging to reuse or recycle such polyurethane foams. The reprocessing of polyurethane is usually a slow process, especially for those prepared from petroleum-based...

Self-Healing Polymers with Shape Recovery
Reduces the need for hands-on repairs, saving time and moneyThese self-healing polymers spontaneously mend wear-related fissures and cracks to increase the lifespan of many different products, including components for airplanes and spacecraft. Traditionally, when an item such as a machined component showed signs of wear-and-tear, a human fixed or replaced...
