Design of new degradable polyurethanes inspired by biodegradation mechanisms

2 Design of new degradable polyurethanes inspired by biodegradation mechanisms 

The study of PU degradation mechanisms has motivated the development of novel degradable PU materials from 2005 to 2015, particularly in the area of tissue engineering (TE) applications. Specifically, chennical linkages that are susceptible to oxidative, hydrolytic, or enzymatic degradation have been incorporated into the segmented block copolymeric structure of new PU materials to achieve desirable degradation processes.
