▎ 摘　　要

NOVELTY - Modified reduced graphene oxide microfine fiber comprises reduced graphene oxide and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT) as conductive macromolecule polymer, where microfine fiber is continuous, and has regular porous nano-structure on its surface. USE - Modified reduced graphene oxide microfine fiber used in neural tissue scaffold for directional induced neural differentiation of bone marrow mesenchymal stem cell, and used in self-driven nerve repair system for generating powder for promoting bone marrow mesenchymal stem cell differentiation to nerve (all claimed). ADVANTAGE - The modified reduced graphene oxide microfine fiber has good shape, surface appearance and conductivity, and has good adhesion and proliferation ability to bone marrow mesenchymal stem cell. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing modified reduced graphene oxide microfine fiber, which involves carrying out heat treatment of a mixed solution containing graphene and PEDOT at high temperature; (2) a neural tissue scaffold, which comprises modified reduced graphene oxide microfine fiber; and (3) a self-driven nerve repair system, which comprises neural tissue scaffold and self-driven separate friction nano generator, where neural tissue scaffold and separated friction generator generates power for promoting differentiation of bone marrow mesenchymal stem cell into neurons.
