Fluorographene
氟化石墨烯是一種重要的新型石墨烯衍生物。氟化石墨烯與石墨烯相比，雖然碳原子的雜化方式由sp2轉變?yōu)閟p3，但同時也保留了石墨烯的片層結構。因此，氟化石墨烯不但具有石墨烯一般大的比表面積，同時由于氟原子的引入極大地降低了石墨烯表面能，極大地增強了疏水疏油性，提高了熱穩(wěn)定性、化學穩(wěn)定性及抗腐蝕能力。氟化石墨烯的這些獨特性能使其可廣泛應用于抗磨潤滑、耐高溫腐蝕涂層等，同時由于氟化石墨烯的較長帶隙寬使其在納米電子器件、光電子器件以及熱電裝置等領域具有潛在的應用前景。此外，由于氟化石墨烯基氟碳材料具有發(fā)達的比表面和孔結構，且氟含量的不同對能帶結構具有可調節(jié)性，導致其具有獨特的導電性能，用于鋰一次電池正極材料時具有與電解液接觸界面大、鋰離子擴散速度快等特點，用氟化石墨烯做正極材料的鋰原電池具有能量密度高、放電平臺高且平穩(wěn)、使用溫度范圍寬、存儲壽命極長等優(yōu)點，在航空航天和高端民用領域有極大的應用潛力。
Fluorographene is an important graphene derivative. Compared with graphene, fluorographene retained the lamellar structure of graphene although the carbon atoms were hybridized from sp2 to sp3. As a result, fluorographene has not only large specific surface area, at the same time due to the introduction of fluorine atoms, the surface energy of graphene was greatly reduced, the property for hydrophobic and oleophobic was greatly enhanced, while the thermal stability, chemical stability and corrosion resistance were largely improved. Due to its unique properties, fluorographene can be widely used in the fields of anti-wear lubrication, high temperature corrosion resistant coating, at the same time, due to its wider bandgap, fluorographene has potential applications prospect in nano-electronic devices, photoelectronic devices, thermoelectric devices and other fields. In addition, because the fluorocarbon materials have fairly developed specific surface and pore structure and unique conductivity, the lithium primary batteries will have large contact interface with electrolyte and fast lithium ion diffusion speed, when fluorographene used as cathode material of lithium batteries. These lithium primary batteries have the advantages of high energy density, high discharge voltage, stable discharge curve, wide operating temperature, extremely long shelf life, which has great application potential in the aerospace and high-end civil field.
