Abstract: The present invention relates to a durable and multifunctional superhydrophobic coating composition and water based fabrication method of producing the durable and multifunctional superhydrophobic coating composition via chemical modification and functionalization of hydrophilic material by silanes under room temperature without any organic solvents. Synthesis of chemically modified cellulose nanofibers or clay in water forms excellent water repelling thin films upon coating over various substrates. The super hydrophobic materials are used as additive for paints, pigments, paper, varnish and, textile and used for various industrial applications such as construction of buildings and other super structures.
