| 논문초록 | Recent advances in biomaterials research have shown that biopolymers can be served as versatile materials in a variety of applications including filtration membranes. Here we present the potential use of biologically derived melanin as antibacterial agent to mitigate bacterial growth in poly(vinylidene fluoride) (PVDF) membranes. We isolated melanins from dark-color horse fibers (EquusMel) using the acid hydrolysis method. Extracted melanin biopolymers exhibit a homogeneous elliptical microstructure with antibacterial activity. Subsequently, extracted and Synthetic melanins were blended with PVDF to fabricate EquusMel-PVDF and SynMel-PVDF flat sheet membranes via immersed phase inversion method. Morphology and chemical composition of the fabricated membranes were investigated with electron microscopy and spectroscopy methods. The bactericidal activity rates of EquusMel-PVDF and SynMel-PVDF membranes against Escherchia coli and Staphylococcus aureus were 100% and 99.66%, respectively. |
