Description
Summary:We report the fabrication of superhydrophobic Ag nanorods substrate using glancing angle deposition (GLAD) technique. The effect of substrate temperature of Ag nanorods on contact angle was explored. The SEM images clearly confirms the difference in the morphology of the Ag nanorods grown at varying substrate temperature ranging from 313 K to 133 K which affects the roughness and the surface density of the nanostructures formed. We have controlled the size and gap of Ag nanorods to obtain higher surface roughness and reduced the surface energy by heptadecafluoro-1-decanethiol (HDFT) to achieve contact angle above 150°. The measured CA on the uncoated Ag nanorods substrates was 107.1 ± 3° and 134.8 ± 2.5° for the room temperature (RT) and low temperature (LT) Ag nanorods substrates respectively. Maximum contact angle of about 164° ± 4 and 142.2° ± 2 was achieved for the HDFT coated Ag nanorods grown at substrate temperature 133K and 313K respectively.
