[0049] The filler used in this application is not particularly limited, and may be a commercially available commercial product or experimentally synthesized, for example, calcium sulfate, hydrophilic silica or polyimide-coated silica composite particles, but Preferably, the filler is a polyimide-coated silica composite particle, and the preparation method of the polyimide-coated silica composite particle comprises:
[0050] (1) Preparation of naphthalene anhydride-terminated polyimide prepolymer
[0051] Add 0.8-0.98 moles of diamine and an appropriate amount of m-cresol into a completely dry three-necked flask, and stir under the protection of an inert gas. When the diamine is completely dissolved, add 1 mole of dianhydride and 2.0-4.0 moles of catalyst. After stirring at room temperature for 30 minutes, heat to 75-85°C, react for 3.5-4.5 hours, and then at 175-185°C, react for 3.5-4.5 hours; after the reaction, cool down to room temperature, pour the solution into methanol, ...
