Nature has always been an inspiration for scientists, and superhydrophobicity is one prime example of such interest, as exhibited in the lotus leaf. In fact, many researchers have been trying to imitate the hierarchial micro/nanostructures of the lotus leaf to reproduce similar superhydrophobic properties with the hope to obtain new materials with interesting and improved wetting properties [1]. Over the recent years, considerable research has been made to produce fibrous metal oxides-based superhydrophobic nanocomposite surfaces due to their potential applications in a wide variety of sectors such as automotive, aerospace, building and construction and corrosion mitigation [2,3]. The preparation of such inorganic fibrous materials to be incorporated in the polymeric matrices could lead to a new generation of superhydrophobic materials with outstanding water repellency through the cooperative effects of their low surface energy and their surface roughness generated by the fibrous structure. However, the brittleness of inorganic surface fibrous particles considerably limits their practical applications. As such it is a persisting challenge to develop superhydrophobic fibrous nanocomposite materials while retaining their surface morphology. In this communication, we will describe a new efficient synthesis approach for a novel superhydrophobic fibrous epoxy-based materials with enhanced corrosion resistance. The structural characterizations and the anti-corrosive performance of this dendritic superhydrophobic fibrous coating on carbon steel will be also presented and discussed.
