Preparing Hydrophobic Cellulose Nanofibers-SiO₂ Films and Coating by One-Step Mechanochemical Method.

ABSTRACT: Green and sustainable cellulose-based hydrophobic coatings are increasingly the subject of scientific and industrial research. However, few researchers pay attention to preparing it by a one-step method. Therefore, a superhydrophobic coating composed of hydrophobic SiO₂ and cellulose nanofiber modified by 3,4-dichlorophenyl isocyanate was manufactured through one-step ball milling. It was found that the ball milling can promote SiO₂ dispersion and achieve the preparation of modified nanocellulose, which further disperse SiO₂ nanoparticles to form film or coating. Compared with the ultrasonic dispersion method, the composite coating prepared by ball milling method can obtain higher water contact angle and more stable hydrophobic properties. The hydrophobic c
