Synthesis of nanographene (NG) and thermoplastic polyurethane (TPU)/NG nanocomposites by a facile and cost‐effective method was pursued in this work. For that purpose, NG was synthesized via a combination of microwave (MW) and shear mixing done by a simple kitchen blender. Next, TPU/NG nanocomposites were prepared by the kitchen blender in the solution state. Afterward, with variable amounts of the NG, TPU/NG nanocomposites were fabricated and their mechanical and rheological performances were comprehensively studied. It was established that the dispersion quality of NG had a fundamental impact on the rheological and mechanical properties of the fabricated nanocomposites which were even more fascinating than that of other nanofillers. It was discussed and suggested that this interesting presentation might have been originated from the dual role (reinforcement and a lubricant agent) of NG due to its size, dispersion state, and added amount.

纳米石墨烯对TPU / NG纳米复合材料微观结构-性能相关性的双重作用分析

这项工作致力于通过一种简便且经济高效的方法合成纳米石墨烯（NG）和热塑性聚氨酯（TPU）/ NG纳米复合材料。为此，NG是通过微波（MW）和简单的厨房搅拌机进行的剪切混合而合成的。接下来，通过厨房搅拌机以溶液状态制备TPU / NG纳米复合材料。然后，用不同量的NG，制备了TPU / NG纳米复合材料，并对其力学性能和流变性能进行了综合研究。可以确定的是，NG的分散质量对所制造的纳米复合材料的流变和机械性能具有根本性的影响，而这种纳米复合材料比其他纳米填料更具吸引力。
