| titleOfInvention | Method for preparing inorganic nanoparticle/aromatic polyimide composite film and prepared composite film |
| abstract | The invention relates to a method for preparing an inorganic nanoparticle/aromatic polyimide composite film and the prepared composite film. The method comprises the following steps: complexing an aromatic polyimide film containing an imidazole structure with heavy metal ions; carrying out fluorination reaction on the polyimide film with the surface complexed with the heavy metal ions to obtain the polyimide film with the surface containing the carbon-fluorine bond; introducing silicon hydroxyl on the polyimide film through a carbon-fluorine bond to form a polyimide film with the surface containing the silicon hydroxyl, and introducing an inorganic nanoparticle layer through the silicon hydroxyl to obtain the composite film. The method can improve the selectivity of fluorination reaction, thereby improving the content of C-F bonds on the surface of the polyimide film and avoiding chain scission of polyimide macromolecules. |
