Improvement in Mechanical and Thermal Properties of Transparent Semi‐Aromatic Polyimide by Crosslinking

Front Cover: In article number 2000085 by Jianqing Zhao and co-workers, a cyclic-olefin copolymer is employed as a crosslinking agent to prepare crosslinked semi-aromatic polyimide films with improved molecular weight, which is expected to improve the semi-aromatic polyimide films' mechanical and thermal properties, as well as keeping their good optical transparency.
