Production of snake foam based on -nitro aniline (PNA) was considered fun in old-school chemistry laboratories. Herein, we report the fabrication of a new carbon nanomaterial from PNA-based foam. The resulting material, resembling graphene and consisting of nitrogen heteroatoms, is N-doped graphenelike nanostructures, and their morphology, structure, and stability are comprehensively examined using combined techniques including C-13 NMR spectroscopy, X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). An optimized route was also established for their large-scale production. Further experimental validation of them as a nanofiller in polymer [SEBS (20 wt %) and paraffin wax (80 wt %)]-based nanocomposites was carried out, and we found that the thermomechanical properties of the nanocomposites were synchronously improved, which was attributed to the enshrouding effect of the nanofiller to the polymer chains. Owing to their good thermomechanical property and low-cost feature, these new nanomaterials can be further explored as a promising candidate for applications in energy storage, catalysis, and CO capture.
在老式化学实验室中，基于对硝基苯胺（PNA）制备蛇形泡沫曾被视为一种有趣的实验。在此，我们报告了一种由基于PNA的泡沫制备新型碳纳米材料的方法。所得材料类似石墨烯且含有氮杂原子，是氮掺杂的类石墨烯纳米结构，我们使用包括碳-13核磁共振光谱、X射线光电子能谱（XPS）和X射线衍射（XRD）在内的联合技术对其形态、结构和稳定性进行了全面研究。还建立了其大规模生产的优化路线。进一步对它们作为聚合物[SEBS（20重量%）和石蜡（80重量%）]基纳米复合材料中的纳米填料进行了实验验证，我们发现纳米复合材料的热机械性能同步得到改善，这归因于纳米填料对聚合物链的包裹效应。由于其良好的热机械性能和低成本特性，这些新型纳米材料可作为能量存储、催化和二氧化碳捕获应用的有前景候选材料进一步加以探索。
