Popis: 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).
