Abstract This article reports the fabrication, characterization, and evaluation of electrospun nanofibrous membranes consisting of poly (vinylidene fluoride) (PVDF) and cellulose acetate (CA) infused with varying concentrations of titanium dioxide (1 wt%, 3 wt%, 5 wt% and 7 wt%) on the removal of toxic organic contaminant 1,4-dioxane. The formation of nanofibrous membranes and the present distribution of titanium dioxide particles were ascertained using scanning electron microscopy (SEM). The PVDF/CA electrospun membranes were assessed for intermolecular interactions using Fourier transform infrared spectroscopy (FTIR) and antibacterial property. The membranes were tested for suitability in the filtration of 1,4-dioxane (C4H8O2) through the Buchner filtration test. It could be seen that the filtration efficiency of the membranes improved up to 55% upon the addition of TiO2. This revealed that the filtration efficiency of the membranes enhanced by increasing the contents of T iO2. Furthermore, the membranes with T iO2 also exhibited better antibacterial activity against the pathogens viz., Escherichia coli, Pseudomonas aeruginosa Bacillus licheniformis, and Staphyllococcus aureus.
