The Self-Sterilized Properties of Ag@TiO₂-Styrene-Acrylic Complex Coatings

Abstract:

Self-sterilized complex coatings obtained by Ag@TiO₂incorporation into styrene-acrylic latex, extensively used in interior wall coatings, are prepared via a coupling agent modification process. A microscopy (TEM) study shows that the complex latexs obtained are highly homogeneous at the nanometric scale, exhibiting an intimate contact between both the organic and inorganic components. Ag@TiO₂incorporation into this polymer matrix renders self-sterilized nanocomposite materials upon light excitation, which are tested against Escherichia coli and Staphylococcus aureus. the complex coatings display an impressive performance in the killing of all micro-organisms with a maximum for an oxide content between 2-5 wt %.
