Abstract
A super-hydrophobic 2024Al surface with micro- and nano-scale hierarchical crater-like structure has been prepared by constructing the surface and modifying the textured surface with low energy material of HFTHTMS (HFTHTMS = (heptadecafluoro-1,1,2,2-tetrahydrodecyl)trime thoxysilane). The textured surface was characterized by scan electron microscope (SEM) and x-ray photoelectron spectrum (XPS). The SEM image shows the crater-like surface with micro- and nano-scale hierarchical microstructures. The textured surface modified with HFTHTMS has super-hydrophobicity with a contact angle of 162° and the sliding angle of 3°.
