摘要
Carbon aerogels are novel lightweight porous materials with three- dimensional hierarchical structure. They have high specific surface area, high porosity, low density, excellent heat resistance and electrical conductivity. Currently, carbon aerogels have been widely investigated in the applications of strain sensors, supercapacitors, electromagnetic wave shielding, electromagnetic wave absorption, thermal insulation, fire protection，high efficient adsorption and so on. The preparation methods of carbon aerogels include solvent thermal reduction method, freeze-drying method and template method. The applications of several kinds of composite carbon aerogels in strain sensors were reviewed and the development of strain sensors prepared by composite carbon aerogels were prospected. ? 2023 Chengdu University of Science and Technology.
