| titleOfInvention | Wave-absorbing aerogel and preparation method thereof |
| abstract | The invention relates to a wave-absorbing aerogel and a preparation method thereof, belonging to the technical field of functional polymer materials. The preparation method comprises the following steps: dispersing the nano wave-absorbing filler in an alcohol solvent to obtain nano wave-absorbing filler liquid slurry; stirring and mixing the nano wave-absorbing filler liquid slurry, a catalyst and a phenolic solution to obtain a suspension, wherein the solute of the phenolic solution is phenolic resin or a mixture of an aldehyde compound and a phenolic compound, and the mass ratio of the nano wave-absorbing filler to the solute is 1: 4-1000; sealing the suspension, reacting at 100-150 ℃ for 4-8h, then cooling to 50-100 ℃, and reacting for 8-120h to obtain wet gel; and drying to obtain the wave-absorbing aerogel. The aerogel provided by the invention has the functions of ultralight weight, high porosity, heat insulation and wave absorption, and can meet the functional diversification requirement of the aerogel material in the aerospace field. |
