Synthesis and antimicrobial activities of polymer/montmorillonite–chlorhexi…

Abstract. The PDMS/montmorillonite–chlorhexidine acetate (PDMS/OMMT) nanocomposite films were successfully obtained by intercalation from solution. Organo-montmorillonite (OMMT) with antibacterial activity was prepared from Na+-montmorillonite (Na+-MMT) and chlorhexidine acetate (CA) by ion exchange. The microstructure of these nanocomposite films were characterized by TEM and XRD. The ef…
