Patterned polystyrene (PS) nanotube arrays were successfully fabricated using photolithography via the polymer solution-wetting method. The microstructure of these nanotubes was investigated using conventional and high-resolution transmission electron microscopy (HRTEM). Two major types of morphology were observed for these PS nanotubes, one being bamboo-like and the other being barrel-shaped. The multiwetting mechanism was proposed to explain the different morphologies. X-ray diffraction (XRD) showed that the PS nanotubes have a higher degree of crystallinity than bulk PS. In addition, crystalline lattice fringes were observed in some regions of the PS nanotubes using HRTEM. Patterned polymer nanotube arrays could be used for nanocable coating to protect from oxidation and corrosion in nanodevices.
通过聚合物溶液润湿法，利用光刻技术成功制备了图案化聚苯乙烯（PS）纳米管阵列。使用常规和高分辨率透射电子显微镜（HRTEM）对这些纳米管的微观结构进行了研究。观察到这些PS纳米管有两种主要的形态类型，一种是竹节状，另一种是桶状。提出了多重润湿机制来解释不同的形态。X射线衍射（XRD）表明，PS纳米管的结晶度高于本体PS。此外，使用HRTEM在PS纳米管的一些区域观察到了晶格条纹。图案化聚合物纳米管阵列可用于纳米电缆涂层，以保护纳米器件免受氧化和腐蚀。
