通过冷热冲击将合成石墨定制转化为旋转取向错误的少层石墨烯
Tailored conversion of synthetic graphite into rotationally misoriented few-layer graphene by a cold thermal shock
摘要：
随着石墨烯的发现，具有旋转堆垛层错的多层石墨烯（FLG）在电磁、光学和吸收等方面的优异性能引起了人们的广泛关注。随着人们的根本利益的日益强烈，对合成这种FLG的需求也在迅速增加。然而，这种FLG的潜在应用，特别是在复合材料科学和能量存储设备中，实际上受到阻碍，因为不能满足所需的生产率。此外，具有受控层数的这种FLG的合成仍然是未解决的挑战。因此，非常需要在这一方向上取得进一步突破。本文在这方面向前迈出了一步，可能是同类文章中的第一篇。在这里，我们展示了如何这样的FLG，精确控制层数，可以很容易地从一个均衡压实的合成石墨，通过控制动态断裂，与微支化不稳定性，由冷热冲击引起的，并发现这种转变背后的机制，通过理论建模。
英文摘要：
Following the discovery of graphene, keen attentions have been paid in comprehending the noticeably superior electromagnetic, optical and absorptive properties of few layer graphene (FLG) with rotational-stacking-faults. With achieving intense fundamental interests, the demands to synthesize such FLG are rapidly increasing. However, the potential applications of such FLG, especially in composite science and energy storage devices, are practically hindered because of non-fulfillment of required production rate. Additionally, synthesis of such FLG with controlled layer-numbers still remains an unsolved challenge. Further breakthroughs in this direction are thus highly desirable. The present article is a step ahead in this direction and is possibly the first of its kind. Here we show how such FLG, with precisely controlled number of layers, can readily be obtained from an isostatically compacted synthetic graphite, by controlled dynamic fracture, with microbranching instability, induced by cold-thermal-shock and discovered the mechanism behind such transformation by a theoretical modeling.
