在自然，壁虎开发了能够聪明的粘附的复杂粘附结构，它是依附不同光滑、不平的表面的能力，弄平天花板，并且随意分开。壁虎脚头发的层次结构由 microscale setae，分支和 nanoscale spatulae 组成，它在不同表面上贡献他们的强壮的粘附。在这份报纸，我们为制作模仿壁虎脚头发的二水平的高方面比率 microfiber 数组建议一个简单、便宜的方法。SU-8 光致抗蚀剂被使用，单人赛级的 SU-8 microfiber 数组被一个厚电影影印石版术过程获得。单人赛级的 polydimethyl-siloxane (PDMS ) microfiber 数组被 micromolding 进程和主人模板也获得因为这进程用诱导地联合的血浆(ICP ) 被制作技术。与深洞的数组把硅模子用作底层，有 microhole 数组的 SU-8 层用厚电影影印石版术被加到它，它形成了二水平的层次 PDMS microfiber 数组从被复制的一个双栈模子。水接触角度测试证明二水平的层次结构是极其恐水病的(大约 148.5

英文摘要：

In nature, geckos have developed complex adhesion structures capable of smart adhesion, which is the ability to cling to different smooth and rough surfaces, even ceilings, and detach at will. The hierarchical structure of gecko foot hairs consists of microscale setae, branches and nanoscaie spatulae, which contributes to their strong adhesion on different surfaces. In this paper, we propose a simple and low-cost method for fabricating two-level high aspect ratio microfiber arrays that mimic gecko foot hairs. SU-8 photoresist was used and single-level SU-8 microfiber arrays were obtained by a thick film photolithography process. Single-level polydimethyl-siloxane （PDMS） microfiber arrays were also obtained by a micromolding process and the master template for this process was fabricated using inductively coupled plasma （ICP） technology. Using the silicon mold with deep-hole arrays as a substrate, an SU-8 layer with microhole arrays was added to it using thick film photolithography and it formed a double stack mold from which the two-level hierarchical PDMS microfiber arrays were replicated. Water contact angle tests showed that the two-level hierarchical structures are extremely hydrophobic （about 148.5° compared with the Tokay gecko＇s 160°）.
