고분자 LB막의 유기 가스 감지 특성

Characteristics of Organic Gas Sensitivity in Polymer LB Films

We reported the fabrication and thermal cross-linking of the LB files on porous substrates. The monolayers of the polymers which polyion-conplexed with PAA at the air-water interface can be transferred onto solid substrates such as porous fluorocarbon membrane filter and quartz crystal microbalance. The properties of the monolayers and the LB films investigated by $\pi$-A isothem, FT-IR, and SEM will be discussed. In addition, it was attempted to investigate the reaction of polymer LB films in the organic gas surrounding by the use of LB technique.
