Title:
METHOD FOR PREPARING COMPOSITE CONTAINING CNF MIXED WITH BIODEGRADABLE POLYMER TO ENHANCE MECHANICAL CHARACTERISTICS OF BIODEGRADABLE PLASTICS
Document Type and Number:
WIPO Patent Application WO/2023/214638
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method for preparing a cellulose nanomaterial composite and a cellulose nanomaterial composite prepared thereby, the method comprising the steps of: A) generating a cellulose nanofiber suspension in which cellulose is dispersed in ultrapure water; B) mixing the cellulose nanofiber suspension and a polylactic acid powder to generate a slurry; C) drying the slurry to generate a mixed powder in which cellulose nanofibers are mixed with polylactic acid; and D) blending the mixed powder and polylactic acid pellets, followed by extrusion molding, thereby preparing the cellulose nanomaterial composite.
