▎ 摘  要

NOVELTY - Polylactic acid dialysis membrane comprises polylactic acid film, catechin compounds and carboxylated graphene oxide. The catechin compound is adhered to the polylactic acid film. The carboxylated graphene oxide is connected to the catechin compound through a hydrogen bond. USE - Polylactic acid dialysis membrane used in dialyser (claimed). ADVANTAGE - The polylactic acid dialysis membrane is more uniformly distributed on the polylactic acid film and has better blood compatibility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for following: (1) a method for preparing polylactic acid dialysis membrane, which involves preparing polylactic acid dialysis membrane includes applying mechanical force to connect the carboxylated graphene oxide to the polylactic acid film surface-functionalized and modified by the catechin compound; and (2) a dialyzer, which comprises a shell and the polylactic acid dialysis membrane according to any one of claims 1 to 4 filled in the shell.
