| 中文摘要 | preparation of poly(vinylidene fluoride-co-hexafluoro propylene) (f2.6) flat-sheet asymmetric porous membrane has been studied for the first time. factors affecting f2.6 membrane pore structure and permeate performance, such as macromolecule pore formers (polyethylene glycol-400, 1000, 1540, 2000 and 6000), the small molecule former (glycerol), swelling agent (trimethyl phosphate) in casting solution, precipitating bath component and temperature, exposure time and ambient humidity, were investigated in detail. average pore radius and porosity were used to characterize f2.6 membrane structure, and respectively, determined by ultrafiltration and gravimetric method for the wet membrane. morphology of the resultant membranes was observed by scanning electronic microscopy (sem). final test on permeate performance of f2.6 porous membrane was carried out by a direct contact membrane distillation (dcmd) setup. the experimental f2.6 membrane exhibits a higher distilled flux than pvdf membrane under the same operational situations. the determination of contact angle to distilled water also reveals higher hydrophobic nature than that of pvdf membrane. |
