摘要:
A method for preparing a cellulose dispersion includes oxidizing cellulose; preparing cellulose nanofibers by defibrating the oxidized cellulose; and adding a water-soluble polymer and inorganic particles to the dispersion containing the cellulose nanofibers.
摘要:
A carbon particle dispersion having good dispersibility and dispersion stability, and a method for preparing same. The dispersion has, at least, carbon particles, a fibrous polysaccharide having carboxyl groups, and a dispersion medium. The method for preparing a dispersion includes the steps, in this order, of dispersing a polysaccharide having carboxyl groups in a dispersion medium to prepare a preparation solution containing fibrous polysaccharide and the dispersion medium, and dispersing carbon particles in the preparation solution to prepare a dispersion containing the fibrous polysaccharide, the carbon particles and the dispersion medium.
摘要:
A gas barrier sheet material which make effective use of natural resources and which has improved gas barrier properties including oxygen barrier properties, water vapor barrier properties and smell barrier properties, and improved flexibility; a barrier container using the same; and a method for fabricating a sheet material. A sheet material is characterized in that a fine fiber layer and a moisture-retaining layer are stacked on at least one surface of a substrate in such a way that the fine fiber layer and the moisture-retaining layer are in direct contact with each other. The invention is more advantageous when using a substrate, e.g. paper, a nonwoven fabric, or a porous membrane, of which surface profile is not flat and which is inherently susceptible to causing troubles in fabrication processes, such as of soaking, wetting and drying during coating of a coating agent.
