Application of ZnO/rGO/paint composite green environmental decorative materials in indoor living environment for the elderly

Liu Zitong,Liu Jiali

Green water-based paint cannot exhibit antibacterial property. For good antibacterial property, ZnO/reduced graphene oxide (rGO) nanofiller was added. Graphene oxide and ZnO/rGO composite were synthesized. Then, ZnO/rGO/paint composite coating with excellent antibacterial property was prepared. As ZnO content in ZnO/rGO filler is increased, antibacterial property of coating is improved. In fighting against Escherichia coli and Staphylococcus aureus , pristine coating shows low antibacterial rates of 0.50% and 0.48%, respectively. When ZnO was added, antibacterial rates of coating were be increased to 49.31% and 41.67%. When ZnO/rGO filler was used, antibacterial rates were increased to 65.46% and 62.17%. At a higher load of ZnO/rGO filler, antibacterial rates reached 93.37% and 83.38%. Friction coefficient of ZnO/rGO/paint composite coating was decreased to 0.53 compared with original coating. At a higher dose of ZnO/rGO filler, friction coefficient was decreased to 0.40. Properties of ZnO/rGO/paint coating meet a national standard for water-based wood coatings for indoor decoration. This composite coating with excellent antibacterial property and wear resistance can be applied in eco-friendly indoor decoration.
