초록

Poly(isobutylene), polystyrene 및 poly(methyl methacrylate)로 코팅된 quartz crystal microbalance(QCM) 시스템을 구성하여, 매우 낮은 압력에서 benzene, toluene, p-xylene의 흡착량을 측정하였다. 모든 흡착실험에서 QCM 시스템의 공진 주파수 변화는 압력의 증가에 비례하였다. 실험결과로부터 각각의 고분자 필름에 대한 흡착물질의 Henry 상수를 구하였으며 고분자 필름과 흡착물질 사이의 최소 흡착 포텐셜 에너지와 비교하였다. 전체적으로 흡착량과 최소 흡착 포텐셜 에너지는 명백한 상관관계가 있었다.

A quartz crystal microbalance (QCM) system coated with poly (isobutylene), polystyrene, and poly (methyl methacrylate) has been prepared to measure the adsorption amounts of benzene, toluene, and p-xylene at very low pressures. The resonant frequency shift of the QCM system is proportional to the increase in pressure in all experiments. The Henry’s constants for all adsorbates on the polymer films are obtained from experimental data and compared with the minimum adsorption potential energies between adsorbates and the polymer films. In general, there is an explicit correlation between adsorption amount and the minimum adsorption potential energy.
