Scientists have created a cationic acrylate-based composite and investigated it as an antimicrobial hybrid coating for interior walls in buildings. By using 3-(methacryloylamino) propyltrimethyl ammonium chloride (MPAC) and acrylates (BA, MMA) as monomers, a novel antimicrobial cationic acrylate-based copolymers (PAMs) were synthesized from surfactant-free emulsion polymerization (SfEP).


Testing Reveals Coating’s Significant Antimicrobial Activity

The synthesis conditions, structures and physical properties of copolymers (PAMs) and its film (PAMs-F) were investigated through FT-IR, SEM, TEM and scratch test. The results revealed that 6 percent of MPAC and 0.5 percent of KPS enabled the film-forming properties and enhanced conversion rate of PAMs, as well as endowed PAMs-F with significant antimicrobial activity.

Furthermore, the PAMs based coating (PAMs-C) was prepared by PAMs and inorganic fillers. And the antimicrobial activity of PAMs-F and PAMs-C was measured, the effects of cationic monomer and nano-TiO2 were also investigated. The results indicated that PAMs-C was able to protect the building interior wall from microbial contamination.
