MOISTURE-SENSITIVE FILM FOR HUMIDITY SENSOR AND PRODUCTION METHOD FOR SAME

摘要

This moisture-sensitive film for a humidity sensor has a polyimide formed from an organic compound which has amino groups at both ends, and which has one or two phenyl groups bonded in straight-chain fashion to the principal structure, and an organic compound in which both ends of one or more phenyl groups bonded in straight-chain fashion in the principal structure are carboxylic acid dianhydrides. The polyimide is composed of repeating basic units in which one or two phenyl groups, and an imide group bonded to this phenyl group, are contained in the organic compound having amino groups at both ends.
