▎ 摘 要
NOVELTY - A polyurethane-graphene oxide antibacterial hydrogel comprises 90-97 %mass poly( beta -amino ester) and 3-10 %mass graphene oxide. The poly( beta -amino ester) has molecular weight of 10000-30000. USE - Polyurethane-graphene oxide antibacterial hydrogel (claimed). ADVANTAGE - The polyurethane-graphene oxide antibacterial hydrogel has excellent biocompatibility, antibacterial effect and dispersibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polyurethane-graphene oxide antibacterial hydrogel.
