  Abstract

In this study, polyvinyl chloride (PVC), thermoplastic polyurethane (TPU) and polycarbonate (PC) were electrospun in a blended form at diff erent PC contents (1050 wt.%) to serve as nanofi ber membranes. The morphological studies done by SEM images demonstrated that the nanofi ber membranes were electrospun without any bead defects in all conditions and the diameters of the nanofi bers were in the range of 140580 nm. The FTIR test also revealed the presence of all characteristic peaks of the polymers in the blended membrane. Further, contact angle (CA) tests showed that the increase of the PC content improved the hydrophilic properties of the membranes with the decrease of contact angle from 129째 to 80 째 . The mechanical tests also revealed that TPU served a signifi cant role in the elastic behavior and tensile strength of the membranes. The tensile strength and strain of electrospun nanofi ber membranes (ENFMs) were in the range of 3.510.3 MPa and 4156%, respectively. The fi ltration effi ciency of ENMs was evaluated using the submerged system with the humic acid (HA) solution. The obtained results showed that the more porous structure (PC content: 10 wt.%) had higher initial permeation fl ux (110 L.m -2 . h -1 ), but all samples reached a constant fl ux (16.44 L.m -2 .h -1 ) after 240 min. Measurement of the fouling parameters also revealed that the irreversible fouling ratio (IFR) of the membranes was improved by increasing the PC content. The results also demonstrated the better antifouling performance for the blended membrane with 50 wt.% of polycarbonate (fl ux recovery ratio, FRR = 92.6%). The HA rejection measurement also exhibited the enhanced rejection of the foulants (99.3%) by the membrane containing a higher PC content (50 wt.%). The results showed that the PVC/TPU/PC nanofi ber membrane at PC content of 50 wt.% had an excellent fi ltration performance and could be used as a candidate for water treatment purposes.
