COMPOSITION FOR MOISTURE-SENSITIVE MATERIAL, MOISTURE-SENSITIVE MATERIAL AND HUMIDITY SENSOR ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a composition for a moisture-sensitive material excellent in water resistance and long-term stability, the moisture-sensitive material and a humidity sensor element.;SOLUTION: The humidity sensor element comprises a pair of electrodes 12 and 13 on an insulation substrate 11 and a moisture-sensitive film 14. The moisture-sensitive film 14 includes a polymer compound having a structure formed by polymerization of a first polymerable compound having a quaternary-ammonium base and an ethylenic unsaturated reaction group and a second polymerizable compound having an ether group and an ethylenic unsaturated reaction group. An electric conductivity is achieved by the quaternary-ammonium base, and flexibility is enhanced by an organic group including an ether group.;COPYRIGHT: (C)2005,JPO&NCIPI
