  • Patent number: 8663426
    Abstract: The present invention relates to a method of producing a cellulose-fiber flat structure, the method including obtaining a cellulose-fiber flat structure by filtering a fine cellulose-fiber dispersion containing fine cellulose fibers having an average fiber diameter of 4 to 100 nm, using a filter material having a water permeability of not more than 100 ml/m2·s and an initial tensile modulus of 20 MPa or greater. The present invention is able to produce a cellulose-fiber flat structure by efficiently recovering fine cellulose fibers from a dispersion containing fine cellulose fibers having an average fiber diameter at the nano level.

    Abstract: A micro structure which is preferred as an original plate of an antireflection, a mold of nano imprint or injection molding is obtained by a single particle film etching mask on which each particle is precisely aligned and closest packed in two dimensions. A single particle film etching mask is produced by a drip step wherein a dispersed liquid in which particles dispersed in a solvent are dripped onto a liquid surface of a water tank, a single particle film formation step in which a single particle film which consists of the particles by volatizing a solvent is formed, and a transfer step in which the single particle film is transferred to a substrate. The single particle film etching mask on which particles are closest packed in two dimensions, has a misalignment D(%) of an array of the particles that is defined by D(%)=|B?A|×100/A being less than or equal to 10%. However, A is the average diameter of the particles, and B is the average pitch between the particles in the single particle film.
