Polymer solution above a critical concentration is generally required for making a uniform diameter nanofibers by electrospinning. PMMA has the ability of resisting of heat, chemical and weathering. Pre-filters are regularly used in removing particulate contaminants that may cause a deleterious effect on downstream membrane elements such as ultrafiltration and nanofiltration. In view of increasing bacterial resistance to antibiotics and antiseptics, silver coating may be an effective strategy to prevent device-related infections. In this study, the antibacterial nanofibrous scaffolds were achieved by electrospinning of the blend of PMMA/silver using N,N-dimethlyformamide and tetrahydrofuran. As the results, the average diameter of PMMA/silver nanofibers was in the range of 250 ~ 400 nm. The antibacterial activities of nanofibrous mats were confirmed by using the static vial method on Staphylococcus aureus and Klebsiella pneumoniae. |
