Abstract
A method of manufacturing an elastic polymer aerogel material includes dissolving tire waste, the tire waste including natural rubber, synthetic polymers, steel, fillers, and curing systems, in a solvent to form a first mixture and dissolving a polymer having at least one double carbon-carbon bond in the solvent to form a second mixture. The first mixture and the second mixture are combined, wherein the tire waste reacts with the polymer having at least one double carbon-carbon bond to form a reactant gel. The reactant gel undergoes a solvent exchange followed by freeze drying to form the elastic polymer aerogel material, wherein the elastic polymer aerogel material defines a 3D porous structure.
