  • Aqueous composition and a method of producing durable and extremely efficient water repelling superhydrophobic materials at ambient condition thereof
    Patent number: 11945957
    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.
    Type: Grant
    Filed: February 8, 2022
    Date of Patent: April 2, 2024
    Assignee: INDIAN INSTITUTE OF TECHNOLOGY MADRAS (IIT MADRAS)
    Inventors: Pradeep Thalappil, Avijit Baidya, Mohd. Azhardin Ganayee, Jakka Ravindran Swathy
