简介：nanocarbon材料的突出的机械性质，特别碳nanotube(CNT)，为高效的小结构的材料使他们成为最有希望的增强nanofillers之一。然而，复杂然而并非eco友好的表面functionalization处理(例如HNO3氧化)通常是必要的帮助驱散nanocarbon材料进环氧基树脂或造在他们之间的化学契约。此处，氮做了碳nanotube(NCNT)被用来代替CNT增强环氧基树脂树脂，并且NCNT/epoxynanocomposite的机械性质在CNT/epoxynanocomposites上显示出重要优势。制造过程简单、环境地友好，并且避免复杂，弄脏并且精力集中的表面functionalization过程。而且，NCNT/epoxy暂停展出了相对低粘性，它为随后的申请是有利的。NCNT的增强的机制也被建议。现在的工作作为潜在的小结构材料给出一个容易的答案到高效的nanocomposite的准备。
