阶梯锥形结构已在聚（乙二醇）的表面上通过接触一个单一的，相对较短的碳纳米管连接到一个AFM针尖与熔融聚合物表面，然后通过聚合物冷却。纳米管附近的聚合物熔体的冷却是这些金字塔状结构形成的最可能机制。简单的传热计算证实了纳米管长度对聚合物局部固化倾向的影响。
Stepped conical structures have been produced at the surface of poly(ethylene glycol) by contacting a single, relatively short carbon nanotube attached to an AFM tip with the molten polymer surface, followed by polymer cooling. Cooling of the polymer melt in the nanotube vicinity is the most likely mechanism for these ziggurat-like structural formations. Simple heat transfer calculations confirm the effect of the nanotube length on the propensity for local solidification of the polymer.
