Patented technology research and industrialization progress in highly transparent polyimide films
This paper introduced the recent research status in the industrial production of colorless transparent polyimide film and reviewed the research progress in fluorine-substituent,alicyclic moieties,non-plane conjugate structure,sulfone moieties,ester group,amide group,and polymerizable inorganic nanoparticles into the polyimide backbone as main tech-nologies.Finally,the development trends and potential applications of colorless and transparent polyimide film was pros-pected.
