Abstract
Composite material membranes as fibers were produced by using electrospinning technology and these membranes characterized and evaluated their properties and performance in this research. Multi-walled carbon nanotubes impregnated in a polystyrene matrix to produce the composite membranes. The hydrophobicity of the membrane was improved by the composite concept with multi-walled carbon nanotubes because of the migration of MWCNTs into fiber structure with membranes. Field emission scanning electron microscopy used to study the morphologies of the membranes and illustrated the average diameters of produced fibers which found about 1.68-3.2 µm and average pore size which found about 3.6 – 4.7 µm for composite membranes and showed an increasing in fibers diameter and pore size with increasing of the MWCNTs amount while the membranes porosity still high percentage about 98%. Also the polystyrene with MWCNTs showed the ability of membranes to decrease the sulfur content from 2.8% for crude oil and reach to about 1.6 % with polystyrene/2% MWCNTs.
