研究了柔性基底上溶剂引起的薄膜屈曲-脱层的形成和演化。通过光学显微镜观察膜表面，显示出显著的动态屈曲-分层发展和随后的稳定的支化-直化状态。结果表明，引发，传播，以及由此产生的图案的膜的结晶是强烈依赖于溶剂的类型，膜应力，界面粘附力，和膜的厚度。通过合理的化学溶剂配置可以进一步控制屈曲，并用于为不同领域（如微/纳米纤维和光学）的聚合物系统上的图案创建提供有用的信息。
The solvent‐provoked formation and evolution of thin film buckling‐delamination on a compliant substrate have been studied. The film surface is observed by an optical microscope showing a remarkable dynamic buckling‐delamination development and a subsequent stable branched‐straight state. It is revealed that the initiation, propagation, and the resulting patterns of film buckles are strongly dependent on the solvent type, film stress, interfacial adhesion, and film thickness. The buckling could be controlled further by a reasonable chemical solvent configuration and used to provide useful information for the pattern creation on polymer systems in diverse fields, such as micro/nanofabrication and optics.
