The TPP fabrication system used in this thesis integrates femtosecond laser, galvanometer scanner, piezo translation stage, tilting correction stage, planar translation stage, beam splitter, CMOS camera, 10x objective lens with numerical aperture 0.25 and diffractive optical elements. Based on the TPP fabrication system, different dimensions and geometric shapes for hydrophobic microstructures designed according to Cassie-Baxter model were successfully fabricated. Furthermore, by using high power laser, micron resolution planar translation stage and diffractive optical elements (5x5 spots), the fabrication time can be greatly reduced with improved fabrication scale. Therefore, the large scale hydrophobic microstructures can be manufactured with 5mm x 5mm cover area and fabrication time 42 minutes. Then, the contact angle test with 10µL water droplet was applied to prove that the microstructures can make the surface of cover glass hydrophobic. On the other hand, with the beam splitter, CMOS camera and planar translation stage, we can make the TPP fabrication system have the ability of observation and positioning. By this feature, we can locate certain point on curvilinear surface to define the coordinate system then fabricate microstructures on it. After that, micro wire on curvilinear surface can be successfully fabricated with 2mm x 2mm projection area and 13µm wire width. Tien-Tung Chung 鍾添東 2019 學位論文 ; thesis 73 zh-TW |
