Title:
COMPOSITE RESIN COMPOSITION AND METHOD FOR PRODUCING COMPOSITE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/246493
Kind Code:
A1
Abstract:
Provided is a composite resin composition that makes it possible to form a film in which cellulose nanofibers are uniformly dispersed in a resin. Provided is a composite resin composition containing an aqueous dispersion medium, resin particles emulsified in the aqueous dispersion medium, and cellulose nanofibers dispersed in the aqueous dispersion medium, wherein the resin particles include at least one selected from the group consisting of (meth)acrylic resin particles, styrene resin particles, and (meth)acrylonitrile resin particles and, when a sample obtained by applying a solution obtained by diluting the composite resin composition so that the nonvolatile fraction thereof is within the 0.01-0.1 mass% range dropwise to a measurement substrate and drying is observed by atomic force microscope, a structure is observed in which the cellulose nanofibers are dispersed and the resin particles cling to the cellulose nanofibers in the form of particles.
