聚苯乙烯衬底上的超薄氘化聚（甲基丙烯酸甲酯）薄膜之间的界面受到由热激发毛细波组成的色散力驱动的不稳定性。我们研究了这个液/液spinodal脱湿的例子，使用镜面和非镜面中子反射测量来表征埋藏的聚合物界面的不稳定性的长度尺度和增长速度。
The interface between ultrathin deuterated poly(methyl methacrylate) films on polystyrene substrates is subject to a dispersive force driven instability consisting of thermally excited capillary waves. We have studied this example of liquid/liquid spinodal dewetting, using specular and off-specular neutron reflection measurements to characterize the length scale and growth rate of the instability of the buried, polymer interfaces.
