Abstract

We introduce a layered platelet with unique pseudotriangular shape (triangular in shape, but with concave sides and bifurcated vertices) composed of antimicrobial reagents, silver cations and 2-mercaptoethane sulfonate anions. This material exhibits both pearlescent and antimicrobial effects resulting from its structure (layered platelet), and components (antimicrobial reagents), respectively. These pigments are also prepared in a simple one-pot process through precipitation reaction by mixing two aqueous solutions containing silver cations and sodium 2-mercaptoethane sulfonate anions. These unprecedented pigments can be potentially applied as a pearlescent pigment requiring antimicrobial activity. In this study, the adsorption of anionic azo dyes was conducted, and chitosan was used as an adsorbent. In order to increase the adsorption capacity, it was made in a capsule form and an anionic surfactant was used. In order to reuse the capsule as a photocatalyst, silver nanoparticles were coated on the surface of the capsule. It has been shown that self-floating is good for decontamination on the water surface, and that the capsules after dye experiments can be reused through a photocatalyst.
