| titleOfInvention | Porous polyimide ink, preparation method thereof and method for preparing porous polyimide through direct writing 3D printing |
| abstract | The invention provides porous polyimide ink, a preparation method thereof and a method for preparing porous polyimide by direct writing 3D printing, and relates to the field of 3D printing technology and preparation of porous polymer materials. The porous polyimide ink provided by the invention comprises polyamic acid, an organic solvent and a pore-foaming agent. The porous polyimide ink prepared by the invention is applied to direct writing 3D printing, the obtained printing product has excellent formability and good dimensional stability, and the porous polyimide obtained by thermal imidization and post-treatment has uniform aperture, uniform pore distribution and interpenetration of pore channels. The method for preparing the porous polyimide is combined with a 3D printing technology, the problems that the pores of the porous polyimide prepared by a traditional sintering method are difficult to control, a complex porous component is difficult to form and the like are solved, and the method is suitable for 3D printing and forming of porous oil-containing parts working under extreme working conditions and special conditions. |
