12‐4: Composition Optimization of Transparent Glass‐fabric Reinforced Siloxane Hybrid (GFRHybrimer) Films for Thermally Stable Flexible Display Substrate Film

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 o C). Also, the fabricated GFRhybrimer film showed a smooth surface (R rms = 0.265 nm), low coefficient of thermal expansion (~14 ppm/ o C), and high elastic modulus (7 GPa).

P‐69: Light Absorbing Dye‐Doped Siloxane Based Optical Filter Film for Image and IR Sensors

“…Vis dye-doped siloxane based optical filter films for flexible IR long-pass filter film were fabricated in two way: coating film and glass-fabric reinforced siloxane hybrid (GFRHybrimer) film by using light absorbing dye doped siloxane resin according to the purpose. [6][7][8] Coating film has low haze value compare to GFRHybrimer film which is suitable for sensors requiring precision. GFRHybimer film has good mechanical reliability compare to coating film which is suitable for sensors used in harsh condition.…”
