The polymer decoration technique has been widely used to study the chain folding behavior of polymer single crystals. In this article, we demonstrate that this method can be successfully adopted to pattern a variety of polymers on carbon nanotubes (CNTs). The resulting structure is a two-dimensional nanohybrid shish kebab (2D NHSK), wherein the CNT forms the shish and the polymer crystals form the kebabs. 2D NHSKs consisting of CNTs and polymers such as polyethylene, nylon 66, polyvinylidene fluoride and poly(L-lysine) have been achieved. Transmission electron microscopy and atomic force microscopy were used to study the nanoscale morphology of these hybrid materials. Relatively periodic decoration of polymers on both single-walled and multi-walled CNTs was observed. It is envisaged that this unique method offers a facile means to achieve patterned CNTs for nanodevice applications.
聚合物修饰技术已被广泛用于研究聚合物单晶的链折叠行为。在本文中，我们证明了该方法可以成功地用于在碳纳米管（CNT）上对多种聚合物进行图案化。所得结构是一种二维纳米杂化串珠（2D NHSK），其中碳纳米管形成串，聚合物晶体形成珠子。已经制备出了由碳纳米管和聚乙烯、尼龙66、聚偏二氟乙烯以及聚（L-赖氨酸）等聚合物组成的2D NHSK。利用透射电子显微镜和原子力显微镜研究了这些杂化材料的纳米级形态。观察到聚合物在单壁和多壁碳纳米管上都有相对周期性的修饰。可以设想，这种独特的方法为实现用于纳米器件应用的图案化碳纳米管提供了一种简便的手段。
