Abstract

A surface with continuously changed adhesion from ultrahigh to ultralow is fabricated by an integrated method of anodic oxidation combined with octafluorocyclobutane (C4F8) plasma. The control of droplet transport along the direction of the adhesion gradient in length is achieved, as the surface is submitted to either tilted angle or vibration frequency.

摘要

通过阳极氧化与八氟环丁烷（C4F8）等离子体相结合的集成方法制备了一种表面附着力从超高到超低连续变化的材料。当该表面处于倾斜角度或振动频率时，可实现液滴沿附着力梯度方向在长度上的传输控制。
