氟化石墨烯是一种由氟原子与碳原子以共价键紧密结合而成的化合物,以(CFx)n 的化学结构式呈现,其中 x 处于 0 到 1.25 之间的不定值。这一数值的变化直接影响着氟化石墨烯的性质。C/F比值≤1的高氟化度氟化石墨烯具有优良的热稳定性,是电和热的绝缘体,不受强酸和强碱的腐蚀,润滑性能超过MoS2和鳞片石墨烯。C/F比值>1称之为低氟化度氟化石墨烯,低氟化度石墨烯呈灰黑色,热稳定性较差,一般不作润滑剂。但它是制造高能无水电池阴极的理想材料。氟化石墨烯是电池的活性物质。用锂作阳极,氟化石墨烯作为阴极组成非水系电池,理论上,其能量密度约为水系锰电池的5倍,电压为2倍;储藏性能好,没有气体产生,自身放电极小;工作电压平稳,受温度影响小,在-20~70℃范围内照常使用。氟化石墨烯表面能降低、疏水性增强,同时还具有耐高温、化学性质稳定等特点,可以用作隧道障碍或作为高质量的绝缘体或屏障材料,也可用于发光二极管和显示器,在界面、新型纳米电子器件、润滑材料等领域具有广泛的应用前景。

Fluorinated graphene is a compound formed by the covalent bonding of fluorine atoms and carbon atoms, which is presented in the chemical structure of ( CFx ) n, where x is an indefinite value between 0 and 1.25. This change in value directly affects the properties of fluorinated graphene. High-fluorinated graphene with C / F ratio ≤ 1 has excellent thermal stability, is an insulator of electricity and heat, is not corroded by strong acid and alkali, and has better lubrication performance than MoS2 and flake graphene. The C / F ratio > 1 is called low-fluorinated graphene. The low-fluorinated graphene is grayish black, has poor thermal stability, and is generally not used as a lubricant. But it is an ideal material for the manufacture of high-energy anhydrous battery cathode. Fluorinated graphene is the active material of the battery. The non-aqueous battery is composed of lithium as anode and fluorinated graphene as cathode. In theory, its energy density is about 5 times that of the aqueous manganese battery, and the voltage is 2 times. It has good storage performance, no gas generation, and its own discharge is very small ; the working voltage is stable and is less affected by temperature. It is used as usual in the range of-20 ~ 70 °C.Fluorinated graphene has the characteristics of low surface energy, enhanced hydrophobicity, high temperature resistance, and stable chemical properties. It can be used as a tunnel barrier or as a high-quality insulator or barrier material. It can also be used for light-emitting diodes and displays. It has broad application prospects in the fields of interfaces, new nanoelectronic devices, and lubricating materials.
Product Features
1.Good chemical stability : Due to the introduction of fluorine atoms, fluorinated graphene can maintain the stability of structure and properties in many chemical environments. For example, it can maintain its chemical composition under harsh conditions such as strong acid and strong alkali.
2.Unique electrical properties : Different degrees of fluorination will lead to changes in their electrical properties. From insulators to semiconductors, it even exhibits certain electrical conductivity under certain conditions.
3.Low surface energy : This makes it have good hydrophobic and oleophobic properties, and has potential applications in antifouling, self-cleaning and other fields. For example, it can be used to manufacture oil-free surface coatings. 4.Enhanced mechanical properties : Fluorinated graphene may be improved in mechanical properties such as strength and hardness.
