Polyurethane reinforcement elastic nanocomposite crosslinked with single cellulose nanofibrils

摘要

The present invention relates to a polyurethane-based high-strength nanocomposite in which a single-cellulosic nanofiber is crosslinked, and a polyurethane-based elastic nanocomposite according to the present invention is characterized in that a single-cellulosic nanofiber is chemically crosslinked in a three-dimensional network structure to be compared with a conventional polyurethane And the mechanical strength and the dimensional stability against heat are remarkably excellent.;
