高分子薄膜去润湿孔增长动力学

Dynamics of Hole Growing in Polymer Thin Films during Dewetting

高分子薄膜去润湿是近年国内外表界面研究领域的热点.孔增长动力学作为高分子薄膜去润湿动力学的重要组成部分,对其进行深入研究,不仅可以促进人们对高分子薄膜去润湿过程的理解,而且可为高分子表界面图案化设计提供理论依据.近年来,有关去润湿孔增长动力学的理论、实验和计算机模拟工作很多,并且取得了较大的进展.本文综述了这一领域最为重要的研究工作,分析了理论预言与现有实验结果偏离的原因以及由此而呈现的重要问题,并对这一领域的研究方向进行了展望.

Dewetting process of polymer films is a hot science. Hole-growing dynamics is an important part of research and application field in surface and interface the dewetting dynamics,further research on it not only can contribute to our understanding of the dewetting process, but also provide theoretical guidance for the design of polymer patterned surfaces and interfaces. The richness of the properties about the hole-growing dynamics has been the subject of extensive theoretical, experimental and simulation studies and lots of great progresses have been made in recent years. In this paper, our central work is focused on three main problems, including reviewing these most important works, elucidating the difference between theoretical predictions and experimental or simulation results, and proposing the corresponding problems.
