| Summary: | 碩士 === 明志科技大學 === 材料工程系碩士班 === 105 === In this work, we used the stainless steel (SS) mesh as the substrate, vertically aligned carbon Nanotubes (CNTs) were grown on SS mesh via a home-made thermal chemical vapor deposition (CVD). The as-prepared CNTs/SS meshes were utilized in the application of oil water separation.
Due to the three important properties as below, SS meshes were used as the substrate for the study of oil water separation: (1) Anti-corrosion and outstanding mechanical strength to avoid failing by the debris floated on the ocean, (2) easy design for various products, and (3) low cost.
We successfully fabricated the high-density and uniform CNTs on the SS meshes, as-inspired Lotus effect by nature plane, our vertically align CNTs showed outstanding performance of superhydrophobicity.
The CNTs/SS mesh owning a water contact angle of as high as 144° and an oil contact angle of 0°. It is expected that such superhydrophobic and superoleophilic filtering membrane made by CNTs/SS mesh can be widely used for continous oil-water separation in the practical use. The prepared superhydrophobic and superoleophilic CNTs/SS mesh displayed the outstanding performance in the continuous oil-water separating, including easy fabrication process, low cost, large-area production, reusable ability, and rapid collection of various oils from water.
