摘要采用石英晶体微天平（QCM）法对薄膜形成的初始阶段进行了分析。用石蜡薄膜覆盖的QCM的共振频率和电阻表明，即使在从熔体或溶液成膜之前，膜的粘弹性也可以改变，即，可以观察到预转变现象。QCM分析还表明，液晶分子可以作为固相吸附在界面附近，即使在双相液晶相。
ABSTRACT The initial stage of film formation has been analyzed using the quartz crystal microbalance (QCM) method. The resonance frequency and resistance of the QCM covered with paraffin thin film indicate that the viscoelastic properties of films can be changed even before the film formation from the melt or the solution, i.e., pre-transition phenomena can be observed. The QCM analysis also reveals that liquid crystalline molecules can be adsorbed as a solid phase in the vicinity of the interface even in the nematic liquid crystal phase.
