Robust transparent glass-fabric reinforced plastic (FRP) films for flexible electronic substrate platform

Abstract

Optically transparent plastic films are developed by impregnating glass-fabric with refractive index matched siloxane hybrid resin (GFRHybrimer films). These films exhibit low thermal expansion coeffiecient (< 15 ppm/°C) and high modulus (> 10 GPa) with high thermal stability up to 350 °C, and are suitable for use in flexible substrate films. Furthermore, transparent conducting electrode (TCE) films are fabricated using metal (Ag or Cu) nanowire or nanotrough which are embedded into the surface of GFRHybrimer films (TCE-GFRHybrimer). The fabricated TCE films represent smooth surface roughness (Rnns ∼ 1 ran), excellent opto-electrical performance (low sheet resistance with high transparency) and thermal/chemical robustness. To demonstrate suitability of the TCE films as a flexible substrate platform, flexible organic light emitting diode (OLED) and perovskite solar cells are fabricated on the TCE films.
