▎ 摘　　要

NOVELTY - A three-dimensional graphene oxide conductive hydrogel preparing method involves adding polycaprolactone-gelatin composite, methacrylic acid-modified gelatin, graphene oxide and initiator into de-ionized water, mixing uniformly to obtain the printing ink and storing for future use. The three-dimensional-Max software design model is utilized for three-dimensional printer control software model, performed slice processing and designed the printing structure of the inner part, transferred the printing ink to the extruding cylinder of the three-dimensional printer and printed to obtain oxidized graphene conductive hydrogel primary product, which is immediately irradiated with UV and solidified to obtain the finished product. USE - Method for preparing three-dimensional graphene oxide conductive hydrogel that is utilized for repairing tissue engineering (claimed). ADVANTAGE - The method enables preparing the three-dimensional graphene oxide conductive hydrogel with high toughness, better elasticity, better biocompatibility and conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a three-dimensional graphene oxide conductive hydrogel.
