Abstract:Colorless polyimides (PIs) have attracted a lot of attention because of the prosperous development of flexible devices. Traditional aromatic PIs possess great thermal stabilities and mechanical properties but lack high transparency. Aliphatic PIs provide great optical transparency, but the poor film formability, low mechanical strengths, and high coefficient of thermal expansion (CTE) make them hard to utilize practically. In this work, we present a series of colorless poly(amide-imide) films consisting of 4,4… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
