Zinc oxide nanorod preparation method

Abstract

The invention discloses a zinc oxide nanorod preparation method and belongs to the field of piezoelectric power generation textiles. The zinc oxide nanorod preparation is characterized by comprising the following steps: dropwise adding ammonium hydroxide into a zinc acetate dihydrate and hexamethylene tetramine water solution to obtain zinc oxide seed crystal liquor; putting the seed crystal liquor into a water bath pot; clamping a textile lining by tweezers, perpendicularly putting into the seed crystal liquor, standing, then pulling the lining out of the liquid level from the solution at a constant speed and finally putting the textile lining with the surface soaked by the seed crystal liquor into an oven to form a seed crystal layer; opening a constant-temperature water bath pot, perpendicularly putting the textile on which the seed crystal layer grows into reaction fluid and wholly soaking a flask into the constant-temperature water bath pot; washing by deionized water after growthfinishes and drying to prepare the zinc oxide nanorods. The zinc oxide nanorods grow and are prepared on the silver-coated textile lining, the nanorods are perpendicularly and tightly arranged on thesurface of the textile, the zinc oxide nanorods have the advantages of obviously semiconductor characteristics and good repetition, and obvious current intensified signals appearing in a zinc oxide growth area shows that the zinc oxide nanorods have excellent piezoelectric property.

Description

technical field [0001] The invention belongs to the field of piezoelectric power generation textiles, and in particular relates to a preparation method of zinc oxide nanorods. Background technique [0002] As the world's energy consumption continues to increase and traditional energy sources continue to decrease, scientists are working hard to find new energy sources to supplement future energy sources. In people's daily life, mechanical energy exists everywhere, such as sound waves of speech, bending of fingers, stretching of muscles, movement of footsteps, and flow of air. If these naturally existing mechanical energy can be converted into electrical energy through some kind of device, the energy problem can be alleviated to a certain extent, which is of great research value. Based on this assumption, a new class of self-driven nanodevices that do not require an external power source has emerged. [0003] As early as the 1960s, some people began to study zinc oxide, and ...
