Abstract

This study aimed to manufacture the environmental correspondence materials with functions of water repellency and antimicrobial activity according to make a surface by the thermal spraying method. For the water repellency characteristic was found on the fluorine-carbon, and the antimicrobial activity was detected by using the CuCl2¤3Cu(OH)2 powders, the thermal spraying coatings were made by the compound wire where two kinds of the powders were added to the aluminum tube. The functions of water repellency and antimicrobial activity were investigated. The results of the experiment show that two kinds of the CuCl2¤3Cu(OH)2 powders were well dispersed and settled. The mean contact angle was 139° tested by the water droplet method, which shows no much different from the contact angle of the coatings made by only the fluorine-carbon filled wire. Furthermore, by adding the CuCl2¤3Cu(OH)2 powders, at the same time as the water repellency characteristic, the remarkable antimicrobial activity was also clarified form the results of the culture experiment basing on the JIS standardization.
