Abstract

The results of studies on the wettability properties and preparation of porous anodic alumina (PAA) membranes with a 3.3 ± 0.2 μm thickness and a variety of pore sizes are presented in this article. The wettability feature results, as well as the fabrication processing characteristics and morphology, are presented. The microstructure effect of these surfaces on wettability properties is analyzed in comparison to outer PAA surfaces. The interfacial contact angle was measured for amorphous PAA membranes as-fabricated and after a modification technique (pore widening), with pore sizes ranging from 20 to 130 nm. Different surface morphologies of such alumina can be obtained by adjusting synthesis conditions, which allows the surface properties to change from hydrophilic (contact angle is approximately 13°) to hydrophobic (contact angle is 100°). This research could propose a new method for designing functional surfaces with tunable wettability. The potential applications of ordinary alumina as multifunctional films are demonstrated.

摘要

本文介绍了对厚度为3.3±0.2μm且具有多种孔径的多孔阳极氧化铝（PAA）膜的润湿性特性及制备的研究结果。展示了润湿性特征结果以及制造工艺特性和形态。与PAA外表面相比，分析了这些表面的微观结构对润湿性的影响。测量了制备态及经过改性技术（扩孔）后、孔径范围为20至130nm的非晶态PAA膜的界面接触角。通过调整合成条件可获得此类氧化铝的不同表面形态，这使得表面性质能够从亲水性（接触角约为13°）转变为疏水性（接触角为100°）。本研究可为设计具有可调润湿性的功能表面提出一种新方法。展示了普通氧化铝作为多功能薄膜的潜在应用。
