| description | The invention relates to a preparation method of polyimide ink for 3D printing. sol-gel is combined with a 3D printing technology, diamine and dianhydride monomers are added to a catalyst to synthesize a polyamide acid solution, silica is added to form polyamide acid sol, the silica and the polyamide acid sol are stirred to form the high-concentration polyimide ink, and the polyimide ink is printed by adopting the 3D printing technology to obtain low-density polyimide gel. The molecular structure is modified to achieve fusion and good processability, and the high-performance polyimide sol is obtained through the 3D printing technology. Polyimide aerogel prepared in the invention has excellent resistance to the high temperature and corrosion, and has a high mechanical strength. Like ultralow-density polyimide aerogel has a good electric conductivity and a high compressibility, can be applied to the spaceflight field to prepare lightweight and high temperature-resistant materials, can beapplied to the wireless |
