采用自催化生长法制备了一维有序的CuO纳米晶阵列。以聚碳酸酯（PC）膜为模板，在硫酸铜溶液中，通过高压（15 V/cm）在铜基底上均匀沉积了Cu（111）核位。根据聚碳酸酯膜的孔径大小，铜核的两种不同尺寸可以很好地控制在50 ~ 60和100 ~ 150 nm的范围内。在氧气气氛中热处理，电沉积铜核转变为CuO纳米阵列。X射线衍射、扫描电子显微镜和透射电子显微镜分析表明，纳米CuO纳米纤维平均长度为8 μ m，密度为10（7）~ 10（8）/cm（2）量级，其平均直径与Cu核的尺寸一致。(C)2003年，美国物理学会。
One-dimensional and well-ordered CuO nanofiber arrays have been synthesized by a processing of self-catalytic growth. Using polycarbonate (PC) membrane as a template, copper nuclei sites Cu(111) were uniformly deposited on copper substrate via a high voltage input (electric field: 15 V/cm) in a copper sulphate solution. According to the pore diameter of PC membranes, two different sizes of copper nuclei could be well-controlled in ranges of 50 to 60 and 100 to 150 nm. With heat treatment in oxygen atmosphere, the electrodeposited copper nuclei were transformed into CuO nanofiber arrays. X-ray diffraction, scanning electron microscopy, and transmission electron microscopy analyses showed that the nanocrystalline CuO nanofibers with a mean length of 8 mum had an average order of 10(7)-10(8)/cm(2) in density, and their average diameters were accorded with the size of Cu nuclei.
