Photoactive antimicrobial hydrogels were produced by incorporating benzophenone (BP) into glutaraldehyde (GA) crosslinked polyvinyl alcohol (PVA). Structural and functional properties of the BP incorporated PVA/GA (BP:PVA/GA) hydrogels were investigated by FTIR, XRD, SEM, and antimicrobial tests. The durability of the functions was also examined by UV‐Vis spectroscopy, HPLC, MS, and antimicrobial tests. The concentrations of BP and GA in the BP:PVA/GA hydrogels affected the formation of the hydrogels as well as their structures. All BP:PVA/GA hydrogels showed antimicrobial abilities under UVA (365 nm) irradiation, and the effectiveness increased as the amounts of BP in the hydrogels increased. In particular, as‐prepared BP:PVA/GA hydrogels exhibited prominent durability in the photo‐induced antimicrobial ability. POLYM. ENG. SCI., 50:1780–1787, 2010. © 2010 Society of Plastics Engineers
