#$%^&*AU2020100277A420200402.pdf#####ABSTRACT The disclosure relates to a cellulose nanofibril-based hydrophobic composite film material and a method for preparing the same. A cellulose nanofibril suspension and nanosilica suspension are prepared respectively; after mixing the two, the mixture is first coated in a coater to form a film, and then the coated film is subjected to vacuum filtration to obtain a composite film with a tensile index of 162 N-m/g. Its unique surface microstructure and excellent superhydrophobic properties make it difficult for water to adhere to its surface, and therefore, it has an important application prospect in the packaging direction.
