NOVELTY - Preparing graphene-molybdenum disulfide composite sponge pressure sensor involves mixing polydimethylsiloxane, sodium chloride and polydimethylsiloxane curing agent in proportion, after stirring thoroughly, performing pressing and heating and curing in turn, taking out and washing until the sodium chloride is completely dissolved to obtain polydimethylsiloxane sponge, dispersing graphite powder and dispersant in deionized water in proportion, peeling off, freezing, drying to obtain graphene powder, dispersing ammonium tetrathiomolybdate powder and graphene powder in proportion In deionized water, stirring uniformly and after standing for a period of time, a mixed solution is obtained. After the polydimethylsiloxane sponge is immersed in the mixed solution, a hydrothermal reaction is performed. After the hydrothermal reaction is completed, cooling down, taking out the reactant, and washing the reactant. USE - Method for preparing graphene-molybdenum disulfide composite sponge pressure sensor. ADVANTAGE - The graphene-molybdenum disulfide composite sponge pressure sensor prepared improves the sensitivity and detection range of the flexible sensor. The structure increases the surface roughness of the sensor, which is good for improving the sensitivity of sensor under the low pressure condition, does not need additional device chemical reagent, the preparation technique is simple and environment-friendly, and good for large-scale preparation. DETAILED DESCRIPTION - Preparing graphene-molybdenum disulfide composite sponge pressure sensor involves mixing polydimethylsiloxane, sodium chloride and polydimethylsiloxane curing agent in proportion, after stirring thoroughly, performing pressing and heating and curing in turn, taking out and washing until the sodium chloride is completely dissolved to obtain polydimethylsiloxane sponge, dispersing graphite powder and dispersant in deionized water in proportion, peeling off, freezing, drying to obtain graphene powder, dispersing ammonium tetrathiomolybdate powder and graphene powder in proportion In deionized water, stirring uniformly and after standing for a period of time, a mixed solution is obtained. After the polydimethylsiloxane sponge is immersed in the mixed solution, a hydrothermal reaction is performed. After the hydrothermal reaction is completed, cooling down, taking out the reactant, and washing the reactant, drying to obtain the graphene-molybdenum disulfide composite sponge. The graphene-molybdenum disulfide composite sponge is adhered to the electrode, and after the electrode is pasted on both sides of the graphene-molybdenum disulfide composite sponge, it is dried to obtain a graphene-molybdenum disulfide composite sponge pressure sensor. An INDEPENDENT CLAIM is included for a graphene-molybdenum disulfide composite sponge pressure sensor.
