Sale price$100.00


Fluorinated Graphene Nanoplatelets: GF-6 is first of a new line of halogenated graphene materials. Fluorinated graphene is a novel graphene derivative. The formation of covalent C-F bonds is accompanied by sp2 to sp3 structural transition of C-C bonds. This results in improved surface activity as well as processability of GNPs. Unlike graphene, GF-6 displays better dispersibility in polar solvents such as DMA, THF, etc. Depending on the F/C ratio, the material exhibits a range from metallic to semiconducting to insulating electronic behavior. GF-6 contains 6 at. % of fluorine and comprised of an average of 37 graphene layers. Our material can be utilized in various applications such as batteries, nanocomposites, epoxies, etc.

Fluorinated graphene is considered as one of important ultrathin solid lubricants or lubricant additive of lubricating oils, lubricating coatings and anti-wear composites because of its low friction coefficient and high durability.

Microstructure of Fluorinated GNPs:

The microstructure of GF-6 has been investigated by the SEM and TEM Imaging. The flakes show wrinkled paper-like structure with a lateral size ranging from 1 μm to 5 μm. The average number of graphene layers obtained from TEM is about 37 layers that is in agreement with flake thickness calculated from surface area measured by Brunauer-Emmett-Teller (BET) technique.

X-ray Photoelectron Spectroscopy (XPS):

In order to analyze the chemical modification of graphene by fluorine, the X-ray Photoelectron Spectroscopy (XPS) has been performed. As expected, in addition to C 1s and O 1s peaks a distinct F 1s peak is detected. A minor oxygen band is attributed to the physically absorbed oxygen on GF-6 surfaces. The content of fluorine in GF-6 is about 6%.

Raman Spectroscopy:

Raman spectroscopy was used for structural assessment of GF-6. In comparison to graphite (red line) that exhibits a distinct G line due to its highly oriented nature, GF-6 shows three signature bands: D band (1350 cm-1), G band (1585 cm-1), and 2D band (2700 cm-1). A strong D band corresponds to edge defects introduced by fluorination and subsequent exfoliation.

Electrical Properties:

In GF-6, a polar covalent C-F bonds form due to the high electronegativity of fluorine. As a result, the material exhibits a metallic behavior that is common for fluorinated graphene at low F concentration [1] and as can also be inferred from FTIR analysis. Although, by introducing a small percentage of F results in the shift in band gap opening, the polarity of C-F bonds still promotes a metal-like behavior. In addition, unlike inert graphene, the presence of F and O surface groups leads to its good dispersibility in number of polar solvents such as THF, DMF, etc. [2]
