Hot Filament Chemical Vapor Deposition of Polymeric Tertiary Amine Containing Nanocoatings For Antibacterial Textile Applications

In this study, poly(diethyl aminoethyl methacrylate) (PDEAEMA) thin films were deposited by hot filament chamical vapor deposition (HFCVD) method on cotton fabric surfaces to prepare antibacterial textile materials. Use of an initiator tert-butyl peroxide (TBPO) during the depositions allowed coatings at low filament temperatures. Deposition rate was measured as 25 nm/min. FTIR analysis of the coatings confirmed the high retention of the tertiary amine functional group that is required for the antibacterial activity. SEM images showed conformal coatings around individual fibers of the cotton fabric.
