Preparation of Zinc Oxide Sub-micron Rod Membrane by Template Method

摘要

We show that a ZnO membrane containing sub-micron structure such as solid rods and hollow tubes can be formed chemically on the polymer template substrate from an aqueous solution at 333 K. This advanced template method was entailed by immobilization of Pd catalyst on the polymer template and optimization of the deposition condition. The dimension of the obtained ZnO rod, the length and the outer diameter are 9 μm and 800 nm, respectively. Therefore, the aspect ratio is 11.25 : 1. A typical electric resistivity of the ZnO membrane was 22.4 Ωcm at room temperature.
