| Abstract: | Cellulose hollow fiber membrane was spun with ionic liquid 1-allylic-3-methyl imidazole chloride(Cl) as solvent.The influence of the molecular weight and the mass fraction of polyethylene glycol(PEG) on the structure and properties of cellulose hollow fiber membrane were investigated.Field emission scanning electron microscopy(FESEM) was used to observe the membrane's inner and outer surface morphology structure.The pure water flux,porosity,maximum tensile strength and elongation of membrane at break were t... |
