Abstract
A preparation method of a conductive elastomer includes the following steps: (1) according to the mass percent of 20˜75%, dissolving the metallic salts into deionized water to form an electrolyte solution, wherein said metallic salts is either of magnesium nitrate, sodium nitrate, zinc nitrate, cesium nitrate, calcium nitrate, neodymium nitrate, aluminum nitrate, potassium nitrate, potassium chloride, magnesium chloride, calcium chloride, sodium chloride, zinc chloride, cesium chloride, aluminum chloride or their combinations; (2) according to the mass percent of 10˜40%, mixing starches into the electrolyte solution prepared in step (1), then at the temperature of 33˜120° C., stirring to gelatinize the starches, forming a viscous liquid; (3) standing the viscous liquid obtained in step (2) at 25˜90° C. for 10 min to 48 h to obtain the conductive elastomer.
