Abstract
Abstract The elastomers with the combination of high strength and high toughness have always been intensively pursued due to their diverse applications. Biomedical applications frequently require elastomers with biodegradability and biocompatibility properties. It remains a great challenge to prepare the biodegradable elastomers with extremely robust mechanical properties for in vivo use. In this report, we present a polyurethane elastomer with unprecedented mechanical properties for the in vivo application as hernia patches, which was obtained by the solvent‐free reaction of polycaprolactone (PCL) and isophorone diisocyanate (IPDI) with N , N ‐bis(2‐hydroxyethyl)oxamide (BHO) as the chain extender. Abundant…
