摘要

Geopolymers are coating materials with excellent properties that have received considerable attention due to their high resistance to weathering, chemical attack, abrasion, and adhesion. This paper further investigates the performance of geopolymer-based coatings by examining the effect of varying percentages of zinc oxide on their antimicrobial and durability properties. The performance of the coatings was evaluated following durability tests with the incorporation of different zinc oxide doping levels. Furthermore, to demonstrate the degree of antibacterial properties of the coating, test plates were treated with two common fungi and bacteria, and the number of bacterial colonies was observed. Results showed good stability and antimicrobial properties when coating with ZnO.
