METHOD FOR PRODUCING POLYIMIDE/INORGANIC COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a colorless and transparent polyimide/inorganic composite material having good heat resistance and flexibility. SOLUTION: The method for producing a polyimide/inorganic composite material comprises causing a semi-aliphatic and/or a complete aliphatic polyimide, which is soluble in an organic solvent having a repeated unit represented by a specific chemical structural formula, to react with a silane coupling agent having reactivity with the terminal groups of the polyimide, and then adding silicon alkoxide and distilled water to conduct a sol-gel reaction.
