摘要研究了硅衬底上液晶5AB 4和5AB 3薄膜的脱湿形态。对于5AB - 4，可以清楚地识别成核和spinodal脱湿，并且从液体剖面的扫描力显微镜可以定量推断有效界面势的细节。由于该系统中润湿力的特殊性，与旋量分解的类比特别接近。对于5AB 3，观察到一个额外的，相当复杂的脱湿情况，这与在初始脱湿过程中形成的液滴结晶有关。
Abstract We have investigated the dewetting morphology of thin films of the liquid crystals 5AB 4 and 5AB 3, from a silicon substrate. For 5AB 4, nucleation and spinodal dewetting can be clearly identified, and from scanning force microscopy of the liquid profiles, details of the effective interface potential can be quantitatively inferred. Due to peculiarities of the wetting forces in this system, the analogy to spinodal decomposition is particularly close. With 5AB 3, an additional, rather complicated dewetting scenario is observed which is connected to the crystallization of droplets which have formed during the initial dewetting process.
