Green phyto technology is a novel version, and the intersection of nanotechnology with nanobiotechnology gains much attention among global researchers owing to the vast range of industrial, environmental and medical applications. To synthesize bimetallic nano particles of Au@Ag, corresponding metal precursors were added to aqueous fruit latex extract of Artocarpus heterophyllus (AHL) & bark latex extract of Mimusops elengi (MEM) and exposed to sunlight. Hydrophobic surfaces are often designed to mimic low surface energy materials and hierarchical micro/nanostructures. In this study, hydrophobic surfaces on glass substrates were fabricated using a simple immersion process that was rapid, facile, and environmental friendly. Latex extracts, Au@Ag nanoparticles, stearic acid and methyltrichlorosilane were used in the coatings. The shape, heterogeneity, roughness and surface functionality of modified hydrophobic surfaces were investigated by FESEM, 3D profilometer and FT‐IR studies. The contact angle (CA) of modified surfaces was measured by Goniometer. The anti‐corrosive property of modified hydrophobic surfaces was tested. Recent micro/nanotechnological advancements have inspired artificial changes of surface wettability by bio‐mimic surfaces with efficient nanoparticles.
