    Abstract: To provide a method for producing a porous film in which even when minute fine particles are used, fine particles can be satisfactorily dispersed, a method for producing a composition for producing a porous film, and a porous film that can be produced by the method for producing a porous film. When a porous film is formed using a varnish including at least one resin component selected from the group consisting of polyamide acid, polyimide, a polyamide-imide precursor, polyamide-imide and polyethersulfone, and fine particles, varnish is produced by dispersing the fine particles by using a pressure device that pressurizes slurry including the fine particles and a dispersing device provided with a flow path whose cross-sectional area is 1960 μm2 or more and 785000 μm2 or less, and allowing the slurry pressurized to 50 MPa or more to pass through the flow path.

    Abstract: A method for preparing a porous fluoropolymer precursor includes combining a fluoropolymer and a removable additive to form a composition, the removable additive having a thermal decomposition temperature greater than a sintering temperature of the fluoropolymer, compressing the composition to form a preform, and sintering the preform to form the porous fluoropolymer precursor. A method for preparing a porous fluoropolymer includes disposing the porous fluoropolymer precursor in a removing agent, contacting the removable additive with the removing agent, and removing, by the removing agent, the removable additive from the porous fluoropolymer precursor to form the porous fluoropolymer, wherein the porous fluoropolymer comprises a plurality of pores formed by removing the removable additive

    Abstract: A thermoplastic sulfur-polymer composite comprises a thermoplastic polymer, such as polyethylene and polystyrene; and a sulfur element. Such sulfur element functions as passive sulfur filler in this composite. The thermoplastic polymer is a polymer matrix; and the sulfur filler is dispersed in the polymer matrix. There is no chemical reaction occurs after the addition of the sulfur filler into the host polymer and no chemical bond formed between the polymer and the sulfur filler. The thermoplastic sulfur-polymer composite can be a nanocomposite by either adding certain nanofillers into the composite or making the sulfur filler as sulfur nanoparticles. With its similar physical properties and lower manufacturing costs, the thermoplastic sulfur-polymer composites are good alternatives of the respective pure polymers.

    Abstract: The present invention provides a porous resinous oil-retaining article, containing lubricating oil, which is excellent in the utilization efficiency of the lubricating oil, has a high mechanical strength, and further allows the resin and the lubricating oil to be combined with each other according to a use and a specification. The present invention also provides a method of producing the resinous oil-retaining article. The resinous oil-retaining article comprises a resinous porous article having interconnected holes which are open to a surface of the resinous porous article; and an oil impregnated into the resinous porous article. The interconnected holes are formed by molding a resin containing a pore-forming substance into a molding and extracting a part of the pore-forming substance from the molding with a solvent which dissolves the pore-forming substance and does not dissolve the resin. An interconnected hole porosity of the resinous porous article is not more than 30%.
