Abstract

Super-hydrophobic surface has been received widespread attention in recent years. Both of the morphology and surface energy of the materials have a significant impact on super-hydrophobic property. A novel method to fabricate super-hydrophobic surface is introduced in the present paper. We try to construct rough structure using samaria-doped ceria by plasma spray-physical vapor deposition method followed by fluorination treatment. During the PS-PVD process, the samples were placed at the different deposition distance with a same straight line for shielding and depositing to realize the surface with different morphology. An island-liked structure consisted of nano particles like the hierarchical structure in lotus leaf were obtained by this process, which realize the superhydrophobic characteristic of the coatings accompany with modification process. Meanwhile, the size of the nanostructure influenced the sliding behaviour of the coating surface. Furthermore, the resultant superhydrophobic surface could withstand repeated tearing by an adhesive tape, exhibiting an excellent stability under extreme conditions.
