Nanofiber dispersion, method of producing nanofiber dispersion, powdery nanofibers obtainable from the dispersion, resin composition containing the powdery nanofibers ad molding material for 3D printer using the resin composition
The present application provides a dispersion dispersed satisfactorily cellulose nanofibers, powdery cellulose nanofibers obtained by pulverizing thereof, a resin composition obtained by blending thereof and a molding raw material for a 3D printer by using thereof. It is possible to obtain a composition uniformly finely dispersed the cellulose nanofibers by treating a mixture containing unmodified cellulose nanofibers and a dispersant using a high speed agitating Medialess disperser, and followed by pulverizing the composition to blend with a resin and a rubber component. Also, a resin composition improved in mechanical properties and heat resistance, obtained by blending the powdery cellulose nanofibers above with a thermoplastic resin or a thermosetting resin, is useful as a molding material for a 3D printer.
PAPER OR PAPERBOARD COATED WITH A FOAM COATING LAYER COMPRISING NANOCELLULOSE
The present invention relates to coated paper or paperboard comprising: a paper or paperboard substrate, and a solid closed cell foam coating layer disposed on a surface of said a paper or paperboard substrate, wherein said solid closed cell foam coating layer comprises a nanocellulose, and a foaming agent. The invention further relates to a food container, preferably a cup, comprising such coated paper or paperboard.
