Document Type and Number:
WIPO Patent Application WO/2018/030392
Kind Code:
A1
Abstract:
Provided is method for evaluating a cellulose nanofiber (CNF) dispersion, the method including: (1) a step of preparing 1.0 mass% of a CNF aqueous dispersion; (2) a step of adding a coloring material into the CNF aqueous solution and stirring with a vortex mixer; (3) a step of sandwiching a film of the coloring material-containing CNF aqueous dispersion between two glass plates such that said film has a thickness of 0.15 mm; (4) a step of observing, with a microscope, the film of the coloring material-containing CNF aqueous dispersion sandwiched between the two glass plates; (5) a step of sorting observed aggregates by size (diameter along major axis) thereof; and (6) a step of calculating a CNF dispersion index from the number of sorted aggregates and evaluating the dispersibility of the CNF aqueous dispersion.
