Recent research has focused on enhancing the properties of polyimide films, particularly their dielectric performance, optical transparency, and thermal stability, to meet the evolving demands of ...
The cut-off wavelength was 290 nm for both endo-meso and exo-polyimide films, and they became transparent at above 350 nm. However, the exo-polyimide showed a higher transparency at around 300 nm.
Polyimide films are used to make flexible printed circuits for laptops, smartphones, tablets, wearables and other devices. Transparent polyimide films are of interest as it will be a substitute for ...
