  • 本論文主要內容為利用具微奈米陣列表面的高分子薄膜,仿壁虎觸手表面紋理構造。利用奈米壓印技術製作具微奈米陣列表面的高分子薄膜,並針對微奈米表面結構之高分子薄膜形成之方式進行探討。在奈米壓印實驗的部分,主要將聚苯乙烯Polystyrene(PS)利用旋轉塗佈機,塗佈於玻璃基板上,再利用加熱台加熱至Tg點以及奈米壓印機壓出奈米陣列之高分子薄膜;最後以掃描式電子顯微鏡Scanning Electron Microscope(SEM)觀察高分子薄膜表面紋理構造並利用原子力顯微鏡(AFM)探討奈米陣列之吸附力。


    The goal of the study was simulated gecko foot-hair structure via polymer film that has micro/nano array surface. Using nano imprinting technology to fabricate nano-array surface of polymer film, and the film manufacture condition have been discussed. In nano imprinting experiment, we use spinning coating machine to coat polystyrene on glass substrate, and imprint nano-array on polymer film by nano imprinting machine when the temperature of polystyrene was heated to the Tg. We observed surface texture by scanning electron microscope, and discussed the adhesive force of nano-array of polymer film by AFM.
