Homogeneous Reinforced

Homogeneous-reinforced (HR) polyvinyl chloride (PVC) hollow fiber membranes consisting of coating layer and matrix layer were fabricated via coating process. The mixtures of polymer solutions were uniformly coated on the homogeneous PVC matrix membrane which was prepared by melt-spinning method. The influences of ethanol composition in water coagulation bath on structure and performance of HR membranes were investigated. The results showed that the pure water flux of the HR PVC hollow fiber membranes increased with the increase of ethanol weight fraction in coagulation bath, while the porosity changed slightly. The increase of ethanol weight fraction in coagulation bath brought about the decrease of the protein permeation flux and rejection rate. The tensile strength of HR PVC hollow fiber membranes was about 9.5 MPa, while the elongation at break was higher than 97 %.

And Performance

Polyethersulfone (PES) hollow fiber membranes have been widely used in many fields, such as ultrafiltration, microfiltration, reverse osmosis, liquid/liquid or liquid/solid separation, gas separation, hemodialysis, and so on. In this paper, the sheet PES hollow fiber membranes were prepared. The morphology and performance of membranes can be controlled. By studying the influence of the compositions and conditions on the morphology and performance of PES hollow fiber membrane, the relationship of morphology and performance of the membrane is acquired. The additives were used such as glycerol, BuOH and PEG. In addition, immerse phase inversion was used as membranes preparation method. The morphology of the membrane was controlled by changing kinds of additive, concentration of additive and so on. It was found that the membrane morphologies were changed by additive obviously. Porosity , pure water flux, scanning electron microscopy(SEM) were used to characterize the morphology and performance of the membranes.
