Scientists describe fabricating antimicrobial cationic acrylate-based composite and investigating it as antimicrobial coatings of interior walls in buildings.
Firstly, utilising 3-(methacryloylamino) propyltrimethyl ammonium chloride (MPAC) and acrylates (BA, MMA) as monomers, a novel antimicrobial cationic acrylate-based copolymers (PAMs) was synthesised from surfactant-free emulsion polymerisation (SfEP).
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 % of MPAC and 0.5 % 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 use to protect the building interior wall from microbial contamination.
