TL;DR: The outstanding crack resistance ability of HFG preserved the sheet structure from destruction due to decreased in-plane stiffness and out-plane stress, thus constructing the tough tribofilm, which makes HFG a promising candidate as advanced lubricant in industrial fabrication.

TL;DR: Selective fluorination for graphene oxide (GO) was realized to prepare highly oxygen/fluorine dual functionalized graphene (OFG) under a mild temperature without damaging the sheet structure and introduced fluorine played an important role in enhancing the tribological performance by self-lubricating behavior.

TL;DR: The ester cross-linking of cellulose nanofibril (CNF) aerogel was carried out by a facile and highly effective gas–solid fluorinating reaction without the assistance of organic solvent, simultaneously endowing the fluorine-treated CNFs (F-CNFs) Aerogel with enduring water-durable and enhanced hydrophilic properties.

TL;DR: X-ray photoelectron spectroscopy directly tracked the atomic percentage of fluorine present and the carbon 1s bonding state, showing that the grafting ratio of diamines gradually increases with increased diamine mass ratio, and varying of the types and orientation of C-F bonds characterized by polarized attenuated total reflectance Fourier transform infrared spectroscopic indicates that "covalent" C-f bonds are more sensitive to the substitution reaction of diamine.

TL;DR: The results of this work indicate that the quantity and location of the C-F bonds in FGO can be controlled by adjusting the species and content of oxygenic groups in the precursor graphene oxide.
