Antimicrobial activity of geopolymers ion-exchanged with copper ions
Source abstract
Abstract
Abstract Geopolymers made from metakaolin and an alkali solution were immersed in a 0.1 mol/L copper chloride solution for 24 h. After the solution treatment, the surface color of the geopolymers changed to green to a depth of 900 μm due to ion exchange with copper ions. To evaluate the antimicrobial activity of the colored portion of the geopolymer, it was ground into 500 μm particles and mixed with a 10:1 mass ratio of oyster mushroom (a wood-rot fungus) and sawtooth oak sawdust. This mixture was placed in a glass bottle at room temperature and 100% relative humidity for one week. The results revealed that the geopolymer ion-exchanged with copper ions suppressed the growth of oyster mushrooms in sawtooth oak sawdust, indicating antimicrobial activity.
