▎ 摘　　要

NOVELTY - A bionic bone material is obtained by using electrostatic adsorption assembly of hydroxyl apatite particle and fibroin on carboxylated modified graphene surface, where the mass ratio of the carboxylated modified graphene, hydroxy apatite and fibroin mass ratio of 1:(1-10):(0.5-5). USE - Bionic bone material. ADVANTAGE - The bionic bone material has better biological compatibility, better biological degradability, better mechanical property, better porosity gradient distribution property and wide application range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a bionic bone material.
