POLYIMIDE FILMS

Research News: Tailored surface and bulk properties of polyimide films have resulted from new technology demands, e.g., the request for stro nger, more dimensionally stable films with lower moisture content. The technology trends parallel the demands of the marketplace as well as the demands of manufacturing The authors present the changes both in t he processing methods and in the backbone of the polyimides-for exampl e, higher molecular weight, new substituents, and new ring formations- that led to improvements to the electrical, optical, and chemical prop erties of the polyimide films.
