| titleOfInvention | Polyimide aerogel with micro-nano hierarchical pore distribution and preparation method thereof |
| abstract | The invention relates to a polyimide aerogel with micro-nano hierarchical pore distribution and a preparation method thereof. The preparation method comprises the following steps: adding the polystyrene emulsion into deionized water, performing ultrasonic treatment, dissolving water-soluble polyamic acid and triethylamine in the obtained polystyrene dispersion liquid, performing sol-gel treatment, freezing the obtained polystyrene/polyamic acid hydrogel, freeze-drying, and performing thermal imidization. The polyimide aerogel prepared by the method is small in mass, high in strength, extremely low in heat conductivity coefficient, cheap and easy to prepare the used pore-forming agent, simple and easy to operate in the aerogel preparation process, low in cost, green and environment-friendly, and applicable to various heat insulation scenes. |
