Investigation on the effects of fabrication parameters on the structure and properties of surface-modified membranes using response surface methodology

Surface Modifying Macromolecules (SMM) were used to alter the hydrophobicity of polyetherimide (PEI) hollow fiber membranes and the effects of three fabrication parameters, which are the mass fraction of PEI and SMM in the casting dope and air gap, on the properties of fabricated membranes were inve...

Investigation on the effects of fabrication parameters on the structure and properties of surface-modified membranes using response surface methodology
