## Abstract A series of hybrid materials incorporating imideβmodified silica (IMβsilica) network structures into a polyimide (PI) matrix were produced with a solβgel technique from solution mixtures of poly(amic acid) and tetraethoxysilane (TEOS) containing alkoxysilaneβterminated amic acids with v
## Abstract Poly(amide imide)βepoxysilane (coupling agent) composites were reacted with silica, a condensation product of tetraethylorthosilicate (TEOS), by a solβgel process and were then cast into films. After this procedure, the chemical characteristics and mechanical and thermal properties were
