Inspired by nature, scientists have developed a number of surfaces with controllable wettability, which can be altered by alterations in surface micro/nanostructures or by changes in chemical compositions. In this article, the control of surface wettability by three kinds of shape-memory micropatterns was reported, which are reversibly transformed between a stretched and an original/recovered state due to the shape-memory properties of poly(ethylene-co-vinyl acetate) (EVA). The surface wettability also varies with the surface micropatterns, and this study demonstrates the surface wettability can be controlled by the reversible transformation of the surface morphology of the micropatterns.

受自然界的启发，科学家们开发了许多具有可控润湿性的表面，这些表面可以通过表面微/纳米结构的改变或化学成分的变化来改变。在这篇文章中，报道了三种形状记忆微图案对表面润湿性的控制，由于聚（乙烯-共-醋酸乙烯酯）的形状记忆特性，它们在拉伸和原始/恢复状态之间可逆地转变（长荣）。表面润湿性也随表面微图案而变化，本研究表明表面润湿性可以通过微图案表面形态的可逆转变来控制。
