▎ 摘　　要

NOVELTY - Preparing high-physical leather by insitu reduction of graphene oxide comprises adding nano graphene oxide dispersion liquid to the acidified acid skin to disperse, adding a specific amount of chromium powder to perform chrome tanning after dispersing, adding reducing agent to carrying out in-situ reduction of the nano graphene oxide after finishing chrome tanning. USE - The method is useful for preparing high-physical leather by insitu reduction of graphene oxide. ADVANTAGE - The method: is simple and environmentally friendly; and has less dosage; and the obtained product has excellent heat conductivity, physical performance, tensile strength, tear strength, absorption performance of the chromium in tanning.
