Embodiment Construction
[0013] The technical solution of the invention will be further elaborated below in conjunction with the embodiments.
[0014] Using the 80MeV energy and 20nA current provided by the HI-13 tandem accelerator of China Institute of Atomic Energy 32 S ion irradiation 20μm thick polycarbonate film or polyester film, the irradiation density is 10 8 -10 9 piece / cm 2 . The irradiated sample was placed in a clean and dry environment for a period of time, and after cleaning with alcohol, the two surfaces of the sample were irradiated and sensitized by ultraviolet light with a wavelength of 360nm for 1 hour, so that photooxidation occurred in the latent track As a result, the track hole is deepened or widened, increasing the etching rate Vt of the track. Finally, etching is carried out in a constant temperature bath. The etching conditions are: NaOH solution, the concentration is 6mol / L-7mol / L, the temperature is 55°C-65°C, the etching time is 6min-18min, and the pore diameter is 100...

Abstract
The invention discloses a method for preparing nano zinc oxide wires by using solid nuclear track technology. In the method, through nuclear pore film with a pore diameter of 100 to 600 nanometer is used as a template, a 110-to-200-nanometer-thick gold layer is plated on one side of the nuclear pore film, and a 10-to-40-micrometer-thick copper layer is deposited on the gold layer electrochemically; then a platinum wire is used as an anode and a gold, copper substrate is used as a cathode, zinc oxide is electrochemically deposited to form zinc oxide nanowires, wherein electrolyte is mixed solution of 0.05 to 0.2mol/L KCl, 2 to 7mmol/L ZnCl2 and 3 to 8 mmol/L H2O2, the pH value is 6.5 to 7.5, the electrolysis voltage is 0.8 to 1.5V, and the electrochemical deposition time is 1 to 5 hours. The diameter of the produced zinc oxide nanowires is 100 to 600 nanometers, and the length is 5 to 8 micrometers.
Description
technical field [0001] The invention belongs to the technical field of zinc oxide, and in particular relates to a method for preparing nanometer zinc oxide wires by solid core track technology. Background technique [0002] The one-dimensional nano-zinc oxide wire material has quantum size effect, interface effect, and quantum confinement effect, and has excellent properties that other materials do not have in terms of force, electricity, light, and magnetism. At present, the method of gas-liquid-solid growth mechanism is mostly used in the preparation of nano-zinc oxide wires (see literature Huang, M.H.; Wu, Y.; Feick, H.; Tran, N.; Weber, E.; Yang, P.Adv .Mater.2001, 13, 113; and literature Kong, Y.C.; Yu, D.P.; Zhang, B.; Fang, W.; Feng, S.Q.Appl.Phys.Lett.2001, 78, 407.), or chemical vapor deposition Method (see literature Wu, J.2J.; Liu, S.2C. Adv. Mater. 2002, 14, 215.). However, most of these methods use expensive sapphire and single crystal silicon as solid substra...
