초록

Antimicrobial PYA films containing various photoactivators were prepared using a solution casting method. Benzophenone, 4,4'-bis(dimethylamino )-benzophenone, 1-hydroxycyclohexyl phenyl ketone, 2-methyl-4'-(methylthio)-2-morpholinopropiophenone, thioxanthen-9-one, and 4,4'-dihydroxybenzophenone were selected as the photoactive additives. The UV absorption, transmittance and radical formation, thermal stability, structural and antimicrobial properties of the prepared films were examined by ESR, UV-vis, DSC, XRD and an antimicrobial test. The results showed that the UV activated benzophenone, 4,4'-bis(dimethylamino)-benzophenone and thioxanthen-9-one provided excellent antimicrobial properties after UVA (365 nm) irradiation.
