In this context, water-repellent surfaces have been prepared. Thin polymer coatings were successfully fabricated on silk surfaces through the admicellar polymerization technique by using fluoro-surfactant and 1H,1H,2H,2H-perfluorodecyl acrylate (PFDA monomer) system and potassium persulfate (K2S2O8) as an initiator. The water-repellent properties induced to the treated surface were examined by analyzing the halting-time of the waterdrop on its surface and its contact angle values. The structural morphology of the fabricated surface was assessed by SEM (Scanning Electron Microscope) studies. FTIR (Fourier transform infrared) analysis was done to elucidate the structural changes of the surface after the surface modification. Results authenticated that a substantial degree of hydrophobicity has been imparted to the silk surface.
