Preparation of Nanosized ZnO Arrays by Electrophoretic Deposition

We report a novel method for preparing uniform and aligned ZnO nanowire arrays embedded in anodic alumina membranes (AAM) by electrophoretic deposition (EPD). An integrated process combining the preparation of nanometer-sized ZnO particles and the formation of nanosized ZnO arrays by EPD within AAM was reported for the first time. The deposited nanowire arrays were characterized in terms of X-ray diffractometer, scanning electron microscope, and photospectrometer. As compared with other methods for the preparation of nanowire arrays, the proposed method is simple, materials general, and efficient.
