Polyfluoroaniline (PFANI)/organosiloxane hybrid films were directly prepared from PFANI emulsions and γ-glycidoxypropyltrimethoxysilane (GPTMS) through a sol–gel method. The influence of GPTMS/FANI molar ratios on the morphology and properties of PFANI/GPTMS hybrid films was characterized by fourier-transform infrared, scanning electron microscopy, thermo gravimetric, contact angle measurement and potentiodynamic polarization analysis. It was found that the hybrid films are highly water repellent. In addition, increasing the GPTMS content could significantly improve the thermal behavior and corrosion resistant ability of the hybrid films. However, the water repellency decreases slowly as the GPTMS/FANI molar ratio increases.
