초록

고분자막 습도센서의 감습재료로 사용하기 위하여 vinylbenzyl chloride (VBC), methyl methacrylate (MMA) 그리고 2-hydroxyethyl methacrylate (HPMA)의 여러 가지 조성의 공중합체를 합성하여, 이를 전극에 도포하고 N, N, N', N'-tetraethylene diamine으로 4차 암모늄화 시켜 최종 습도센서를 제조하였다. 상대습도에 따른 저항 변화를 측정한 결과, 공중합체에서 MMA의 조성이 증가하면 저항이 증가하였으며, HEMA의 도입은 친수성기의 작용으로 저항의 증가는 크지 않았으며 강습막의 기판과의 접착성은 크게 향상되었다 또한 VBC/MMA/HEMA=80/10/10의 경우 히스테리시스는 ± 2%RH 안에서 나타났으며, 온도의존성 계수는 -0.42~-0.46%RH/ ? C 이었다. 30%RH, 60%RH 그리고 90%RH에서의 저항 값은 각각 3.0M Ω ,,200k Ω 그리고 9k Ω 이었다.

he copolymers with various composition of vinylbenzyl chloride (VBC), methyl methacrylate (MMA), and 2-hydroxyethyl methacrylate(HEMA) were synthesized as a humidity sensitive material and quaternized with N, N, N', N'-tetraethylene diamine.. Resistance versus relative humidity decreased with increase in the content of MMA in the copolymer. The introduction of HPMA increased the resistance of the humidity sensor as well as enhanced the adherence to the alumina substrate. In the case of VBC/MMA/HEMA=80/10/10, the hysteresis and temperature dependency coefficient were ± 2%RH and -0.46~0.42%RH/ ? C . The average resistance at 30%RH, 60%RH and 90%RH were 3.0M Ω ,200k Ω and 9k Ω, respectively.
