In general, the polyimide(PI) films have good thermal stability, good mechanical strength.In electronic materials, polyimideshows good performance because of its properties. However,polyimide films havelow water sorption property.For electrochemical usage ofpolyimide films, water sorption behavior is important factor. In this work, thepolyimide films are synthesized from various dianhydrides and aliphatic diamines. To compare with aromatic polyimide, Kepton was synthesized with thermal imidization method. Water sorption behavior measured with Thin Film Water Sorption Analyzer(TFWA) which was self-developed. |
