Abstract:

Polymides are of great polymeric material because of the superior mechanical and thermal properties. Thus, they are used in various industries as film, adhesive and insulator material for high-performance applications. Inorganic fillers have been added to the polymers in many applications. Of these, silica particles have been extensively used since they offer cost-effective production. In the present study, the influence of mesoporous silica on the chemical properties of polyimide was investigated. For that reason, the produced Pi/mesoporous silica composites were prepared by in situ polymerization having different mesoporous silica content. Afterward, chemical characterization was determined with FTIR. It was seen that some shifts were observed in the Pi/silica composites. Si-based Pi revealed minor chemical alteration over the Pi.
