| titleOfInvention | A polyimide filter membrane, its preparation method and application |
| abstract | The invention is applicable to the technical field of thin film materials, and provides a polyimide filter membrane, a preparation method and application thereof. The material composition of the polyimide filter membrane is the compound A shown in the following chemical structural formula (I), and the number average molecular weight of the compound A is 80000-100000, Among them, the for or One of the structural formulas. The polyimide filter membrane provided by the invention has a small pore size and a high retention rate for fine particles in the air; and the polyimide filter membrane material is dense and smooth, and the formed fibers are not easy to fall off and have good stability; in addition , its cost is low, it only needs to be less than one-fifth of the commercial price of the same quality multi-space sampling filter membrane. |
