Abstract:
This method for manufacturing a coating film comprises forming a coating film on a surface of a coating film formation object. This manufacturing method is provided with an electrostatic spray step for electrostatically spraying a composition directly onto the coating film formation object and forming a coating film including a fiber deposit. The composition includes component (a), component (b), and component (c) below. (a): One or more types of volatile substances selected from water, an alcohol, and a ketone. (b): A polymer having coating film forming ability. (c): A liquid agent containing one or more species selected from a polyol and an oil that is liquid at 20°C.

Abstract:
A polyester resin composition containing a polyester resin, and a fine cellulose fiber composite having an average fiber diameter of from 0.1 to 200 nm, wherein the fine cellulose fiber composite contains fine cellulose fibers and hydrocarbon groups being connected thereto via an amide bond. The polyester resin composition of the present invention can be worked into a molded article by thermoforming or injection-molding, and is suitably used for various industrial applications, such as daily sundries, household electric appliance parts, packaging materials for household electric appliance parts, and automobile parts. In addition, the fine cellulose fiber composite has high dispersibility against various resins and can exhibit thickening effects, so that it is suitable as various thickeners or the like.
Abstract:
PROBLEM TO BE SOLVED: To provide a composite material having practically sufficient mechanical strength with little load to the environment. SOLUTION: The composite material is obtained by mixing micro cellulose fibers having a 0.1-3 mmol/g carboxyl group content with a moldable polymer material selected from the group consisting of polymers derived from biomass and polymers derived from petroleum. As the polymer derived from the biomass, a polylactic acid or pulp is preferable. The content of the fine cellulose fibers is preferably 0.01-60 mass%. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a suspension of cellulose fibers, which is suitable for producing a gas barrier film restraining the permeation of various gases such as oxygen, water vapor, carbon dioxide, nitrogen and limonene. SOLUTION: The suspension of cellulose fibers contains cellulose fibers, which have ≤200 nm average fiber diameter, the cellulose of which has 0.1-2 mmol/g carboxy group content and which contain the metal selected from a polyvalent metal and a monovalent metal (excluding sodium alone) for forming a counter ion of the carboxy group. The polyvalent metal or monovalent metal for forming the counter ion is preferably selected from cobalt, magnesium, calcium, aluminum and silver. COPYRIGHT: (C)2010,JPO&INPIT
