Optimizing Fabrication of Electrospinning Nanofiber Membranes for Water Filtration using Response Surface Methodology

Nanofiber Polyethersulfone (PES) membrane fabrication using the electrospinning method incorporating dry/wet phase inversion was investigated. The process is a straightforward and versatile to produce one-dimensional nanostructures, especially nanofibers. electrospun’s outcome can be affected by various parameters solution parameters, making it an interesting study subject opportunity for customized nanofiber membrane. In this work, analysis includes dope formulation parameter influence morphology dimensional structure based on Scanning Electron Microscopy (SEM) filtration capability. Fibrous membranes were electrospun at 1 3 ml/h feeding rate 12 25kV voltage in fixed 10 cm distance between filter syringe needle tip. PES with N-methyl-2-pyrrolidone (NMP) as solvent onto wet base (5A 90 mm Advantec Filter Paper) refine fabricated fibrous induce dry-wet process. results indicate that fiber dimension reduced lower higher rate. terms of liquid separation performance, experimental showed pure water permeation flux increased flow spinning 3ml/hr but triple times than concentration formulation, even spinning. performance polyethersulfone also explained Response Surface Methodology (RSM). It focused polymer content, tip-to-collector distance, toward diameter contact angle. Among these factors, effect content (f-value = 65.87) most significant, followed 11.26) 2.59).
