摘　　要：在低温条件下,以纤维(棉纤维、尼龙纤维、铜丝、银丝、头发)为模板,通过简单的化学溶液生长,合成由ZnO纳米棒组成的分级结构,ZnO纳米棒竖直包覆在纤维表面,生长密集,棒的直径约几百纳米,长度为2～3μm.该方法可以以织物纤维(棉纤维、尼龙纤维)、金属细丝(铜丝、银丝)和动物毛发(头发)为模板合成由ZnO纳米棒组成的分级结构,具有一定的普适性.该分级结构比表面积较大,同时可以通过组合构成二维或三维结构,在传感器和太阳能电池等方面具有重要的潜在应用价值.The ZnO hierarchical nanostruetures were synthesized by a simple chemical solution method under a low temperature condition using fiber （cotton fiber, nylon fiber, copper filament, silver filament and hair） as template. The ZnO nanorods covered on the fiber surface vertically and densely. The diameter of ZnO nanorod was about several hundred nanometers and the length was about 2 - 3 micrometers. The fiber of fabric （ cotton fiber, nylon fiber） , metal filament （ copper, silver） and animal hair （ human hair） could be used as template to synthesize ZnO hierarchical nanostructure, which was universalistic. The ZnO hierarchical nanostructure had a larger specific surface area and could be assembled into two- dimensional or three-dimensional structures which could have important potential applications in sensors and solar cells.
