Method for improving antibacterial property of tetrapod-like zinc oxide whisker

Abstract

A method for improving the antibacterial property of a tetrapod-like zinc oxide whisker comprises the steps of A. adding the tetrapod-like zinc oxide whisker taking the shape of white powder in an aqueous solution of potassium sodium tartrate to form paste or suspension and stirring for 10-30 minutes, wherein the mole ratio of the potassium sodium tartrate to the tetrapod-like zinc oxide whisker is (0.1-1):100; then under the state of stirring, slowly adding an aqueous solution of copper chloride with the same molar weight as the potassium sodium tartrate; later continuing stirring for 30-60 minutes; at last, conducting filtering, washing and drying, thus obtaining tetrapod-like zinc oxide whisker compound powder with nanometer cupric tartrate in-situ deposited on the surface; and B. increasing the temperature of the compound powder to 270-300 DEG C, keeping the temperature for 15-60 minutes, and conducting cooling to room temperature, thus obtaining the tetrapod-like zinc oxide whisker with strong antibacterial property. The powder obtained by the method has strong antibacterial capability, sterilizing rate of 98.5%-99.9%, low cost, does not change color when in use and is easy to popularize.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial agent material, in particular to a preparation method of a tetraacicular zinc oxide whisker composite antibacterial agent material. Background technique [0002] Harmful bacteria exist in various places around us, such as the floor and wall of the house we live in, the furniture we use, home appliances, clothing and daily necessities, etc. In 1996, a nationwide outbreak of O-157 Escherichia coli infection in a large area in Japan not only claimed many lives, but also caused global panic. According to statistics, the number of deaths caused by bacterial infection in the world is close to 20 million every year, accounting for more than 30% of the total number of deaths; the cross-bacterial infection rate of various hospitals exceeds 10%. To effectively prevent the generation and growth of bacteria, the use of antibacterial materials is the simplest and most effective method. Antibacteria...
