Abstract： |
The present invention relates to directional nanometer zinc oxide stick or linear film and its preparation process, and belongs to the field of low-dimensional nanometer film material technology. The present invention adopts hydrothermal deposition process, in which zinc salt solution in molar concentration 1-25 mM and amine surfactant solution are mixed homogeneously and set inside stainless steel reactor with PTFE lining, substrate of glass, polymer, inorganic metal, non-metal or other material and with directional texture ZnO crystal seed is set inside the lining, so as to react at 50-150 deg.c for 1-6 hr. After cooling naturally, directionally grown and high crystallized ZnO nanometer stick array film or nanometer stick of diameter 10-500 nm may be form. The process has low synthesis temperature and easy control, and the grown ZnO film is well directional. The present invention is suitable for industrial production of directional nanometer ZnO stick or film. |
