To obtain a surface with water-repelling and self-cleaning abilities attracts much interest in the nanotechnology age. In this study, a perfluroalkyl surfactant (perflurodecanoic acid, PFDA) was coated on nano-sized boehmite surfaces to obtain hydrophobic nano-particles via surface modification. Then the hydrophobic boehmite was coated on a transparent plastic film using spin-coating to obtain a hydrophobic film. The effects of various amounts of hydrophobic polymer on the adsorption behavior and contact angle for hydrophobic properties were investigated using FTIR, and a contact-angle meter. The adsorption of PFDA onto the surface of boehmite takes place through ionic bonding. The contact angles of the thin film prepared by spin coating PFDA-modified-boehmite on glass substrates were above 150°C as the adsorption of PFDA onto the surface of boehmite reached saturation.
