Preparation, characterization, and properties of fluorine-free superhydrophobic paper based on layer-by-layer assembly

A fluorine-free superhydrophobic paper was prepared by a facile method involving layer-by-layer deposition of cationic starch and sodium alginate together with subsequent modification of trichloromethylsilane has been reported in this article. The surface chemical compositions, potentials and surface morphologies of the modified papers were characterized, respectively. The wetting abilities and physical strength properties of the modified papers...
