| titleOfInvention | Preparation process of anti-warping polyimide film |
| abstract | the invention relates to the technical field of polyimide film preparation, in particular to a preparation process of an anti-warping polyimide film, which comprises the following steps of calcium molybdate nano powder preparation, modified nano powder preparation, polymer resin synthesis, resin regulation and film formation, wherein KH550 is used for modifying the surface of calcium molybdate nano particles, so that the nano particles are prevented from agglomerating in the polymer resin through the volume steric hindrance of a long-chain organic part, meanwhile, the compatibility between inorganic nano particle calcium molybdate and an organic polymer is increased, the nano particles are more uniformly dispersed in a polyimide matrix, a continuous and complete three-dimensional network is formed in the KH550-CaMoO 4 nano particle polyimide matrix, the rigidity of a polymer molecular chain is enhanced, the acting force between the molecular chains is enhanced, the energy required by bending and breaking of the polymer molecular chain at high temperature is increased, and the prepared film has good anti-warping performance. |
