RESEARCH ON MANUFACTURING ANTIBACTERIAL PAINT FROM NANOCOMPOSITE ZnO/ PORPHYRIN MATERIALS BASED ON PHOTOCATALYST REACTION

Abstract

Currently, antibacterial paints have very high prices due to the use of
expensive nano silver materials, or are low effective due to the use of nano
TiO2 which can only use UV rays (accounting for 5% of visible light). Paints that
use antibacterial active ingredients from natural raw materials (polyphenols,
isoprenoids, essential oils, natural antibiotics) have too short a shelf life and
are not suitable for application in paint (use time). Use of wall paint for at least
5 years). Therefore, the group proposed to research and manufacture
ZnO/porphyrin nanocomposite materials with high antibacterial activity, low
price, long usage time and application in antibacterial paint.
