Abstract: An object of the present invention is to provide a laminated film that exhibits superior water repellency and oil repellency and has good adhesion between a substrate film and a coating layer, and for this purpose, the laminated film is a laminated film comprising a substrate film and at least one coating layer laminated on the substrate film, wherein the coating layer contains an acid-modified polyolefin and hydrophobic oxide particles, and the acid-modified polyolefin has an acid value of 1 mgKOH/g or more and 60 mgKOH/g or less. Preferably, the laminated film is a solution means in which a surface of the coating layer has a contact angle with respect to water of 100 degrees or more.

Abstract: [PROBLEM] To provide a laminated film having a coating layer surface which exhibits superior water-repellent and/or oil-repellent characteristics, [SOLUTION MEANS] A laminated film in which a coating layer is laminated, directly or indirectly by way of another layer, over a substrate film, the laminated film being such that the coating layer is an outermost layer on at least one face of the laminated film, and hydrophobic oxide particles of average primary particle diameter not less than 10 nm but not greater than 300 nm are present in the coating layer in an amount that in terms of solids content is not less than 30 mass % but not greater than 100 mass %.

Abstract: A carbon electrode material is disclosed for a redox flow battery that particularly, even when using an Mn—Ti type electrolyte, while stabilizing Mn ions and suppressing a rise in cell resistance during initial charge and discharge, has excellent oxidation resistance. The electrode material includes a carbonaceous fiber, and a carbonaceous material for binding the carbonaceous fiber, and satisfies the requirements: (1) when the size of a crystallite in a c axis direction found by X-ray diffraction in the carbonaceous material (B) is Lc(B), Lc(B) is 10 nm or greater; (2) when the size of the crystallite in the c axis direction found by X-ray diffraction in the carbonaceous fiber (A) is Lc(A), Lc(B)/Lc(A) is 1.0 or greater; and (3) the number of bonded oxygen atoms of the carbon electrode material surface is 1.0% or greater than the total number of carbon atoms of the carbon electrode material surface.
