In this current study we have fabricated nonwoven filter membrane of polyacrylonitrile (PAN) that consists of antifouling and antibacterial capacity. Bleaching powder (BP) was incorporated through PAN fiber during electrospinning using blend solution of BP nanoparticles (NPs) and PAN. The morphology and composition of the composite BP/PAN fibers were observed by field scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and energy dispersive spectroscopy (EDS). The obtained results revealed that sufficient amount of BP NPs were effectively loaded on/into PAN fibers. The presence of BP on/into PAN fibers could significantly increase the hydrophilicity of PAN membrane which indicated that as-fabricated membrane can be used not only for bacterial destruction but also for introducing antifouling activity on the membrane. Significant increase in hydrophilicity of composite membrane compared to the pristine PAN membrane and excellent antibacterial activity of BP loaded PAN fibers indicated that this composite membrane will be a potential water filter media to provide pure drinking water.
