セルロースナノファイバー成形体
Document Type and Number:
Japanese Patent JP6990132
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a molded article which comprises cellulose fibers as a principal component and which has excellent strength and low temperature dependence of the strength.SOLUTION: A cellulose nanofiber molded article of the present invention comprises cellulose fibers containing cellulose nanofibers as a principal component, where the cellulose fibers further contain pulp; a content of the pulp based on the cellulose fibers is 0.1% by mass or more and 70% by mass or less; an elastic modulus (E) at 25°C calculated by a nanoindentation method is 3,000 MPa or more and 20,000 MPa or less, and a ratio (E/E) of an elastic modulus (E) at 90°C calculated by the nanoindentation method to the elastic modulus (E) at 25°C is 0.5 or more. The pulp described above is preferably beaten pulp. A content of the cellulose nanofibers based on the cellulose fibers is preferably 50% by mass or more.SELECTED DRAWING: Figure 1
