NOVELTY - Preparation of high-sensitivity reticular graphene/elastomer strain sensor includes ultrasonically dispersing graphene oxide in water to obtain graphene oxide dispersion; cleaning cotton wool bandage as template with water and ethanol, drying, vacuumizing, soaking to graphene oxide dispersion, taking out, drying, heating, and lowering temperature to obtain reticular graphene; and placing into glass slide, connecting both ends with copper, placing silver paste to eliminate interface resistance, coating with butylpyrrole, drying, cooling, spraying elastomer latex, and curing. USE - Method for preparation of high-sensitivity reticular graphene/elastomer strain sensor (claimed) used for wear-resistant electronic device. ADVANTAGE - The method is mild in condition, low in cost, and has high repeatability. The strain sensor is capable of sensing tiny strain, and has excellent deformation ability and high sensitivity. DETAILED DESCRIPTION - Preparation of high-sensitivity reticular graphene/elastomer strain sensor comprises: (A) ultrasonically dispersing graphene oxide in water at 40-100 kHz to obtain graphene oxide dispersion; (B) cleaning cotton wool bandage as template with water and ethanol, drying, vacuumizing, soaking to graphene oxide dispersion for 0.5-2 hours, taking out, drying to 55-65 degrees C for 1-2 hours, drying to 75-85 degrees C for 1-3 hours, heating to 250-310 degrees C for 2-3 hours, and lowering temperature to 750-850 degrees C for 1-2 hours to obtain reticular graphene; and (C) placing into glass slide, connecting both ends with copper, placing silver paste to eliminate interface resistance, coating with butylpyrrole, drying, cooling to room temperature, spraying elastomer latex, and curing at 50-80 degrees C.
