Abstract: Films with optical transmittance of >80% between 400 and 750 nm and with CTEs less than 20 ppm/° C. are prepared from aromatic polyamides that are soluble in polar organic solvents yet have Tgs >300° C. The films are crosslinked in the solid state by heating at elevated temperatures for short periods of time in the presence of multifunctional epoxides. Surprisingly, the optical and thermal properties of the films do not change significantly during the curing process. The temperature required for the crosslinking process to take place can be reduced by the presence of a few free, pendant carboxyl groups along the polyamide backbones. The films are useful as flexible substrates for electronic displays and photovoltaic devices.
Abstract translation: 在400至750nm之间，具有小于20ppm /℃的CTE的光学透射率的膜由可溶于极性有机溶剂但Tg> 300℃的芳族聚酰胺制备。膜在 在多功能环氧化物存在下，在高温下短时间加热固态。 令人惊奇的是，在固化过程中，膜的光学和热学特性没有显着变化。 交联过程所需的温度可以通过沿聚酰胺主链存在少量游离的羧基而降低。 这些膜可用作电子显示器和光伏器件的柔性基板。

Abstract: Films with optical transmittance of >80% between 400 and 750 nm and with coefficient of thermal expansion less than 20 ppm/° C. are prepared from aromatic polyamides that are soluble in polar organic solvents yet have glass transition temperatures >300° C. The films are crosslinked in the solid state by heating at elevated temperatures for short periods of time in the presence of multifunctional epoxides. Surprisingly, the optical and thermal properties of the films do not change significantly during the curing process. The temperature required for the crosslinking process to take place can be reduced by the presence of a few free, pendant carboxyl groups along the polyamide backbones.

Abstract: The present disclosure is directed toward solutions, transparent films prepared from aromatic copolyamides, and a display element, an optical element or an illumination element using the solutions and/or the films. The copolyamides, which contain pendant carboxylic groups are solution cast into films using cresol, xylene, N,N-dimethylacetamide (DMAc), N-methyl-2-pyrrolidinone (NMP), dimethylsulfoxide (DMSO), or butyl cellosolve or other solvents or mixed solvent which has more than two solvents. When the films are thermally cured at temperatures near the copolymer glass transition temperature, after curing, the polymer films display transmittances >80% from 400 to 750 nm, have coefficients of thermal expansion of less than 20 ppm, and are solvent resistant.
