| Abstract: | The PAN hollow fiber is reinforced with inorganic particles, and then the CS/PAN-SiO 2 hollow fiber composite membrane is prepared on the basis of the treatment of the substrate under drawing and heating. The influence of the reinforced substrate and the different operation conditions on the separation performances of the composite membrane is studied. The results show that this kind of composite membrane has an excellent separating performance toward alcohol-water system. |
