摘要： A porous membrane of vinylidene fluoride resin, including a 10 μm-thick portion contiguous to one surface thereof which comprises network resin fibers having an average diameter of at most 100 nm and shows a porosity A1 of at least 60% as measured by a focused ion beam-scanning electron microscope, and showing a surface pore size of at most 0.3 μm on said one surface thereof. The porous membrane has a treated water side surface layer showing a small surface pore size suitable for water filtration treatment and formed of extremely thin network resin fibers giving an extremely high porosity, thus showing an excellent minute particle-blocking performance and also extremely good anti-soiling resistance and regeneratability. The porous membrane is produced by a process including: melt-extrusion of a composition obtained by adding to vinylidene fluoride resin of a large molecular weight a relatively large amount of a polyester plasticizer which is mutually soluble with the resin and provides the resultant mixture with a crystallization temperature that is substantially identical to that of the vinylidene fluoride resin alone to form film, followed by cooling from one side of the film to solidify the film, extracting the plasticizer and stretching the membrane after the extraction while partially wetting a surface portion thereof.

摘要： A porous membrane of vinylidene fluoride resin, comprising a substantially single layer membrane of vinylidene fluoride resin having two major surfaces sandwiching a certain thickness, including a dense layer that has a small pore size and governs a filtration performance on one major surface side thereof, having an asymmetrical gradient network structure wherein pore sizes continuously increase from the one major surface side to the other opposite major surface side, and satisfying conditions: (a) the dense layer includes a 5 μm-thick portion contiguous to the one major surface showing a porosity A1 of at least 60%, (b) the one major surface shows a pore size P1 of at most 0.30 μm, and (c) the porous membrane shows a ratio Q/P14 of at least 5×104 (m/day·μm4), wherein the ratio Q/P14 denotes a ratio between Q (m/day) which is a value normalized to a whole layer porosity A2=80% of a water permeation rate measured at a test length L=200 mm under the conditions of a pressure difference of 100 kPa and a water temperature of 25° C., and a fourth power P14 of the pore size P1 on the one major surface. The porous membrane is produced through a process including: extruding a melt-kneaded mixture of a vinylidene fluoride resin and a plasticizer through a die into a form of a film, followed by cooling, to form a solidified film; and extracting the plasticizer to recover a porous membrane; wherein the plasticizer is mutually soluble with the vinylidene fluoride resin at a temperature forming the melt-kneaded mixture and further satisfies properties: (i) giving the melt-kneaded mixture with the vinylidene fluoride resin with a crystallization temperature Tc′ (° C.) which is lower by at least 6° C. than a crystallization temperature Tc of the vinylidene fluoride alone, (ii) giving the cooled and solidified product of the melt-kneaded mixture a crystal melting enthalpy ΔH′ (J/g) of at least 53 J/g per weight of the vinylidene fluoride resin as measured by a differential scanning calorimeter (DSC), and (iii) the plasticizer alone showing a viscosity of 200 mPa-s-1000 Pa-s at a temperature of 25° C. as measured according to JIS K7117-2 (using a cone-plate-type rotational viscometer).

摘要： A hollow-fiber porous membrane of vinylidene fluoride resin, satisfying: a ratio Pmax/Pm of at most 2.0 between a maximum pore size Pmax and an average pore size Pm, and a Pm of 0.13 μm-0.25 μm, according to the half-dry/bubble point method (ASTM F316 and ASTM E1294); a coefficient of variation in outer surface pore size of at most 70%, and a porosity of 75-90%. The hollow-fiber porous membrane has a moderate average pore size, has a pore size distribution which is uniform as a whole and also on the outer surface, and has a high porosity, so that it shows not only a good pure water permeability but also retains a good water permeability even in continuous filtration of cloudy water. The hollow-fiber porous membrane is produced through a process which includes: melt-extruding a vinylidene fluoride resin together with a plasticizer and a good solvent therefor into a hollow-fiber film, cooling and solidifying the film, extracting the plasticizer and good solvent, omitting a heat-treatment for crystallization, and stretching the hollow-fiber after the extraction at a limited temperature range of 80-95° C. which is higher than a conventional stretching temperature.
