Abstract
Poly[(mercaptopropyl)methylsiloxane] (PMMS)-based antibacterial polymer coatings have been prepared through a two-step sequential thiol–ene click chemistry utilizing 1-allyl-3-decylimidazolium bromide (ADIm) as antibacterial monomer and triallyl cyanurate (TAC) as the crosslinker. These films with different content of ADIm were characterized by thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA) and pencil hardness. It was found that the mechanical and thermal properties of these films were largely influenced by the content of ADIm in the films. Films with imidazolium bromide groups displayed excellent antimicrobial activity against Staphylococcus aureus with 100% killing efficiency.
