Abstract

Special porous anodic aluminum oxide (AAO) membranes are created on Al in a phosphonic acid electrolyte solution through one-step anodic oxidation and modified with polydimethysiloxane using a vapor deposition technique. In this context, the anodic oxidation time is tuned during its process. As such, the Al surface's wettability, and self-cleaning property are controlled by the tunable anodic oxidation time, for the anodic oxidation, time can regulate the structure of the AAO and the proportion of the air-liquid interface.

摘要

特殊的多孔阳极氧化铝（AAO）膜是通过一步阳极氧化在磷酸电解液中的铝上形成的，并通过气相沉积技术用聚二甲基硅氧烷进行改性。在这种情况下，阳极氧化时间在其过程中进行调整。因此，通过可调的阳极氧化时间来控制 Al 表面的润湿性和自清洁性能，对于阳极氧化，时间可以调节 AAO 的结构和气液界面的比例。
