Preparation and properties of photosensitive polyimide /titana-silica hybrid materials

A complex inorganic-polymer hybrid material of polyimide /titania-silica with photolithographic property was prepared by sol-gel process. Polyimide (PT) was based on benzophone-3,3',4,4'-tetracarboxylic dianhydride (BTDA) and 4,4'-diamino-3,3'-dimethyl- diphenylmethane (MMDA) and...

Zusammenfassung:A complex inorganic-polymer hybrid material of polyimide /titania-silica with photolithographic property was prepared by sol-gel process. Polyimide (PT) was based on benzophone-3,3',4,4'-tetracarboxylic dianhydride (BTDA) and 4,4'-diamino-3,3'-dimethyl- diphenylmethane (MMDA) and is negatively photosensitive. The introduction of titania leads to increased refractive index while the introduction of silica leads to improved thermal stability of the hybrid.
