NOVELTY - Stress sensing conductive aerogel comprises a three-dimensional network framework structure composed of stable dispersion, ethylene glycol solution, ferric chloride, ethylene glycol mixed solution, deionized water, polyvinyl alcohol aqueous solution, polyethylene glycol 4000, polyethanol, and nano cellulose suspension, where, the stable dispersion is prepared from graphene oxide and ethanol solution, and the polyvinyl alcohol aqueous solution is prepared from polyvinyl alcohol and deionized water. USE - Used as a stress sensing conductive aerogel. ADVANTAGE - The stress-sensing conductive aerogel has highly developed porosity and excellent elasticity, increased the contact points between the graphene/nano silver wire sheets, reduced resistance, improved conductive performance, larger compressibility, stronger the conductivity, and realizes the graphene/nano silver composite material fusion, and is environmentally friendly, recyclable and degradable material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing stress sensing conductive aerogel comprising (i) preparing stable dispersion: slowly adding the graphene oxide into the ethanol solution, and performing ultrasonic dispersion; (ii) preparing graphene/nano silver wire dispersion liquid: firstly adding the stable dispersion liquid of step (i) into glycol solution for pre-heating, then adding ferric chloride and glycol solution, continuously heating, then gradually adding glycol mixed solution prepared by uniformly mixing silver nitrate and polyvinylpyrrolidone; and stirring and reacting at constant temperature, and then cooling to room temperature, using ethanol and deionized water to wash the product, at last, using deionized water to re-ultrasonically disperse the product, obtaining graphene/nano silver dispersion; (iii) preparing stress sensing conductive aerogel: firstly adding polyvinyl alcohol into deionized water, stirring and heating to polyvinyl alcohol to completely dissolve at 95 degrees C constant temperature water bath, obtaining polyvinyl alcohol aqueous solution; then dissolving the PEG 4000 and the ethanol in the polyvinyl alcohol aqueous solution, then adding nano cellulose suspension; then adding graphene/nano silver dispersion liquid of step (ii), fully stirring, allowing to stand to remove air bubbles to obtain the mixed solution; then pouring the mixed solution into the template, and circulating freezing and thawing for many times to obtain the hydrogel, and then dipping the hydrogel into the deionized water to replace the polyethylene glycol in the gel to obtain the porous hydrogel; at last, freezing the porous hydrogel, and vacuum drying to obtain the stress sensing conductive aerogel.
