NOVELTY - Preparation of elastic and conductive aerogel with ultralow density and ultrahigh specific surface area involves mixing resorcinol and deionized water, stirring, adding formaldehyde solution and sodium carbonate, stirring for 15-30 minutes, adding graphene oxide dispersion, adding dispersion to a closed vessel, maintaining at 60-80 degrees C for 3-15 days to obtain a hydrogel, acidifying, aging, performing solvent exchange, extracting, drying, carbonizing and cooling to room temperature. USE - Preparation of elastic and conductive aerogel for elastic sensor, separation and adsorption materials, electrode materials and hydrogen storage materials. ADVANTAGE - The elastic and conductive aerogel with ultralow density and ultrahigh specific surface area is produced economically. DETAILED DESCRIPTION - Preparation of elastic and conductive aerogel with ultralow density and ultrahigh specific surface area involves mixing resorcinol and deionized water in weight ratio of 1:5-80, stirring, adding formaldehyde solution, stirring for 15-30 minutes, adding sodium carbonate, stirring for 15-30 minutes, adding graphene oxide dispersion, adding dispersion to a closed vessel, maintaining at 60-80 degrees C for 3-15 days to obtain a hydrogel, acidifying, aging for 6-8 days, performing solvent exchange with acetone, extracting with supercritical carbon dioxide, drying to obtain organic aerogel, carbonizing at 150 degrees C for 2 hours, increasing temperature to 200-300 degrees C for 25-35 minutes, heating at 400-600 degrees C for 30-60 minutes, 700-800 degrees C for 1-2 hours and 900-1100 degrees C for 1-3 hours, and cooling to room temperature.
