Abstract

Abstract : This work introduces dual dynamic covalent bonds in the network of a non-isocyanate polyurethane prepared using a cyclic carbonate derived from CO2 to realize self-healing and reprocessing at a low temperature (50 °C) or under UV light. Abstract : Non-isocyanate polyurethanes prepared using cyclic carbonates derived from epoxy soybean oil and CO2 can exhibit the reprocessing ability and facilitate the realization of carbon neutrality, but the relatively high temperature required for the reprocessing is not conducive to application. In this work, a NIPU with a dual dynamic network was designed to achieve reprocessing and self-healing under mild conditions.
