Abstract

Abstract : Composition of siloxane hybrid material (hybrimer) was optimized to fabricate glass‐fabric reinforced siloxane hybrid (GFRHybrimer) with high transparency and thermal stability. Refractive index of the hybrimer was precisely controlled by changing the phenyl precursor and adding a low refractive index crosslinker monomer. By measuring the thermal stability of GFRHybrimer films fabricated with a refractive index matched using cycloaliphatic epoxy oligosiloxane (CAEO), we obtained an optimal CAEO composition. The optimized GFRHybrimer film showed a high transparency (90%) and good thermal stability (1% weight loss temperature of 365 ° C). Also, the fabricated GFRhybrimer film showed a smooth surface (Rrms = 0.265 nm), low coefficient of thermal expansion (~14 ppm/ ° C), and high elastic modulus (7 GPa).
