Abstract

The key component currently missing for the next generation of transparent and flexible displays is a high-performance polymer material that is flexible, while showing optical and thermal properties of glass. It must be transparent to visible light and show a low coefficient of thermal expansion (CTE). While specialty plastics such as aromatic polyimides are promising, reducing their CTE and improving transparency simultaneously proved challenging, with increasing coloration the main problem to be resolved. We report a new poly(amide-imide) material that is flexible and displays glass-like behavior with a CTE value of 4 parts per million/°C. This novel polymer was successfully used as a substrate to fabricate transparent and flexible indium-gallium-zinc oxide thin-film transistors.

摘要

下一代透明柔性显示器目前缺少的关键组件是一种高性能聚合物材料，该材料具有柔韧性，同时具备玻璃的光学和热性能。它必须对可见光透明，并具有低热膨胀系数（CTE）。虽然诸如芳香族聚酰亚胺之类的特种塑料很有前景，但同时降低其CTE并提高透明度却颇具挑战，主要问题在于颜色加深。我们报道了一种新型聚（酰胺 - 酰亚胺）材料，它具有柔韧性，CTE值为百万分之四/°C，呈现出类似玻璃的特性。这种新型聚合物已成功用作基板，用于制造透明柔性铟镓锌氧化物薄膜晶体管。
