Characterization of functional electrospun polymeric nanofiber membranes

EVOH/biochar membranes (diameters 900–1000 nm) were fabricated through lab-made electrospinning technique. SEM, FTIR and DSC were used to characterize the nanofiber membranes. Results revealed that 1.5% biochar loading is the best loading ratio for two reasons: ease of production and the enhancement of filtration. Beyond this loading value, agglomeration hinders the growth of nanofiber matrix. Mechanical properties showed higher tensile modulus for membranes of 1.5% biochar. Efficiency of filtration was verified by using particles with variable size ranging from 30 to 2000 nm. Removal efficiency up to 94.5% of 300 nm particles was achieved. The cost-effectiveness and durability were demonstrated by the reusability, i.e., the efficiency could be sustained up to 93.79% in the first 6 cycles and reduced to 85% after 14 cycles, then reached 76.7% after 20 cycles. Such properties, combined with the economy, durable and easy to scale-up production confirmed the effective utilization of the membranes.
