中文摘要	flat-sheet microporous membranes from f2.4 for membrane distillation (md) were prepared by phase inversion process. dimethylacetamide (dmac) and liclo(4)(.)3h(2)o/trimethyl phosphate (tmp) were, respectively, used as solvent and pore-forming additives. the effects of casting solution composition, exposure time prior to coagulation and temperature of precipitation bath on f2.4 membrane structure were investigated. the morphology of resultant porous membrane was observed by scanning electron microcopy. some natures of f2.4 porous membrane after drying in air, such as mechanical properties and hydrophobicity, were exhibited and compared with poly(vinylidene fluoride) (pvdf) membrane prepared by the same ways. stress-at-break and strength stress of f2.4 microporous membrane are higher than that of pvdf membrane, and elongation percentage of f2.4 membrane at break is about eight-fold as great as that of pvdf membrane. contact angle of f2.4 microporous membrane to water (86.6 +/- 0.51degrees) was also larger than that of pvdf mernbrane (80.0 +/- 0.78degrees). md experiment was carried out using a direct contact membrane distillation (dcmd) configuration as final test to permeate performance of resultant microporous membrane.
