| titleOfInvention |
A solvent-resistant and highly dimensionally stable cross-linked polyimide film |
| abstract |
The invention provides a cross-linked polyimide film with solvent resistance and high dimensional stability, the transmittance of 400nm wavelength light can reach more than 80%, the glass transition temperature is more than 340°C, and the tensile strength is 150MPa Above, the solvent resistance index is within 1%. At the same time, the present invention also proposes that the cross-linked polyimide film be used in optoelectronic display devices, as well as other products and parts that have high requirements on light transmittance and solvent resistance. |
