Abstract: | There has been a growing interest in developing antibacterial polymeric materials The logical consequence following development of a new material is optimisation of its processing conditions and investigation of the Influence Of processing parameters oil functionality of a given material The present work deals with investigation of the effect of preparation temperature oil the mechanical and antibacterial properties of polymer films based oil poly(vinyl alcohol) (PVA) and silver nitrate (0. 1, 3, 5, 7. 9 wt% silver content) The mechanical properties of the films prepared at various temperatures (25, 35. 50. 60, 75 degrees C) were characterized by using stress-strain analysis Antibacterial properties were determined by using an again diffusion test and a dilution and spread plate technique against both Gram positive (Staphylococcus aureus) and Grain negative (Escherichia coh. Pseudomonas aeruginosa and Klebsiella pneumomae). The results show significant effect of the elevated temperature on the samples properties (C) 2009 Elsevier Ltd All rights reserved | ||||||||||
