摘要：
The resistance and frequency change of a quartz crystal microbalance during toluene absorption was measured for poly(vinyl acetate) (PVAc) with 268 nm thickness. Solubility of toluene in PVAc were measured at temperatures from 25 degrees C to 42 degrees C and pressures up to 28.4 torr. The frequency of a quartz crystal microbalance increased with increasing temperature and decreased with an increase in toluene vapor pressure. The resistance of a quartz crystal microbalance increased with increasing toluene vapor pressure and decreased with an increase in temperature. A greater pressure of toluene results in a greater solubility of the toluene into the PVAc film. The change of solubility was calculated by Sauerbrey equation.
