| titleOfInvention | Preparation method and product of polyimide-based composite aerogel |
| abstract | The invention discloses a preparation method of polyimide-based composite aerogel and a product thereof. The polyimide-based composite aerogel comprises the following raw materials: one or more water-soluble polyimide precursors, such as polyamic acid and graphene oxide. The preparation process comprises the following steps: (1) uniformly mixing the water dispersion of graphene oxide and water-soluble precursor polyamide acid of polyimide according to a certain proportion, and preparing graphene oxide-polyamide acid aerogel through a sol-gel process and a freeze-drying technology; (2) preparing the graphene-polyimide aerogel through a thermal imidization process. The method for preparing the polyimide composite aerogel is simple and feasible, and the prepared composite aerogel is controllable in microscopic morphology and adjustable in performance. In addition, the prepared polyimide-based composite aerogel has excellent flame retardance and is an ideal heat-insulating material and flame-retardant material. |
