Aromatic polyamide films for solvent resistant flexible substrates |
| 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. |
