Abstract 

This work is focused on modification of cellulose filters surface in order to hydrophobise a material and decrease water drop adhesion to its surface. Proposed modification methods include deposition of silica particles to obtain desired material roughness and coating material with 1H,1H,2H,2H-perfluorooctyl triethoxysilane (FOTS) to decrease its surface energy
