Water and antimicrobial agent permation of PU and PHEMA membranes in relation to their surface and bulk properties

Four types of polyurethane (PU) and two types of 2-polyhydroxyethylmethacrylate (PHEMA) membranes were prepared by convenient methods. Surface properties, water and antibacterial agent permeabilities of PU membranes were investigated. Water permeability values were determined in the region of 2000 g/m2.24 h. The membranes were found to have sufficient permeability toward antibacterial agents of 1% Silver Sulfadiazine and Bacitracin 10,000 UI-Neomycin sulphate 100 mg ointment.
