Abstract

This paper briefly introduces bio-based degradable polyurethanes from natural bio-based degradable polyurethanes and synthetic bio-based degradable polyurethanes. After a series of experimental studies, the synthetic synthesis of castor oil-based polyurethane porous sponge, polyhydroxybutyrate valerate-based polyurethane and polyvinyl alcohol-based polyurethane was carried out, focusing on its mechanical properties and preparation process, aiming to provide some reference for the development of related work.
