| titleOfInvention | A kind of polyimide composite film and preparation method thereof |
| abstract | The present invention relates to a kind of preparation methods of polyimide composite film, the method is that modified phyllosilicate is added into polyimide preformed polymer, and polymerization obtains polyimide polymer solution, coats later on substrate, elevated cure obtains polyimide composite film；The phyllosilicate of the modification is the phyllosilicate that surface has amido functional group.Polyimide composite film thermal stability provided by the invention is greatly improved, and thermal decomposition temperature can be improved 25 DEG C, and mechanical performance is greatly improved, and tensile strength can reach 113.7MPa, and Young's modulus can increase to 2536MPa；The modifying process of polyimide composite film provided by the invention is simple, and modified feedstock is at low cost. |
