Poly[(mercaptopropyl)methylsiloxane] (PMMS)-based antibacterial polymer coatings prepared by a two-step sequential thiol-ene click chemistry

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. Films with imidazolium bromide groups displayed excellent antimicrobial activity against S. aureus with 100% killing efficiency.
