Description

technical field [0001] The present invention relates to the technical field of polyvinylidene fluoride composite materials, and more particularly, the present invention relates to a preparation method of a nanocellulose-reinforced polyvinylidene fluoride composite material. Background technique [0002] Cellulose nanofibers (CNF) and cellulose nanocrystals (CNC) are collectively referred to as nanocellulose, because cellulose nanofibers can be dispersed into a three-dimensional network structure in water, and the unique three-dimensional network structure can disperse and stabilize particles, and Because cellulose nanofibers can be separated from light substances such as food and organic resins, and further disperse the separated cellulose nanofibers into some inorganic substances and even metals, cellulose nanofibers are widely used. [0003] In the prior art, cellulose and polyvinylidene fluoride are sometimes mixed in different ways to prepare polyvinylidene fluoride with...
