▎ 摘　　要

NOVELTY - Preparing graphene two-dimensional grid structure comprises adding graphene and dispersant into the solvent, uniformly dispersing to obtain stable graphene suspension, adding dimethyl silicone polymer PDMS main agent into the graphene suspension liquid, evaporating part of solvent to obtain graphene dispersion liquid, adding PDMS curing agent into the graphene dispersion liquid to obtain the graphene printing slurry, using the 3 D printer to accumulate graphene printing slurry on the substrate to prepare the two-dimensional grid structure, and solidifying to obtain the graphene two-dimensional grid structure. USE - Method for preparing graphene two-dimensional grid structure used as wearable strain sensor. ADVANTAGE - The method enables to prepare graphene two-dimensional grid structure which is wear resistant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene two-dimensional grid structure
