Plasma Surface Modification of Cotton Fabric by Using Low Pressure Plasma

Environmental issues are to be taken into account when preparing superhydrophobic surfaces for everyday use. Fluorochemicals and organic solvents have potential risks to human health along with environment and their use should be minimized. The present work is to fabricate superhydrophobic surface through post plasma treatment of aqueous extract of rose petals coated on cotton fabric by using oxygen plasma. The contact angle measurement confirms the superhydrophobic nature of the fabric after oxygen plasma treatment. The obtained superhydrophobic fabrics have shown excellent antibacterial activity against E. coli and Staphylococcus aureus. Anti-icing, anticlinging, and other physical properties such as color fastness to light and heat, and superhydrophobicity to tea and coffee droplets have been improved by plasma surface modification.
