Abstract

original image

A novel high-performance transparent glass-fabric reinforced composite film that can be used as a substrate for flexible devices is introduced (see Figure). The composite film exhibited a low CTE (13 ppm K−1), high optical transparency (89%), high thermal stability (378 °C) and excellent flexibility (rollable). The performance of the composite film was successfully tested by fabrication of IGZO TFT and amorphous Si-based solar cells
