Coating of fluorinated alkylsilane on needle-like shaped surface of poly(alkylpyrrole) films was carried out by a facile way. The coated film showed contact angles of larger than 150 degrees and 130 degrees to water and salad oil, respectively. The SEM images showed that the geometrical factor of the film surface did not change during the coating. The film also showed excellent stability to heating and organic solvent treatments, in terms of the contact angles to both water and salad oil. The X-ray photospectroscopic (XPS) and infrared spectroscopic (IR) data revealed that thin layer of condensed heptadecafluorodecyltri-iso-propoxylsilane (HDFDTPS) homogeneously covered on the needle-like surface of the poly (alkylpyrrole) film even though without any thermal treatment.
