Covalent functionalization of strained graphene.
An enhancement of the chemical activity of graphene is evidenced by first-principles modelling of the chemisorption of hydrogen, fluorine, oxygen and hydroxyl groups on strained graphene. For the case of negative strain or compression, chemisorption of the single hydrogen, fluorine or hydroxyl group is energetically more favourable than those of their pairs on different sublattices. This behavi...
متن کاملNon-covalent functionalization of graphene sheets by sulfonated polyaniline.
Graphene sheets were stably dispersed in water by functionalization with sulfonated polyaniline (SPANI), and the composite film of SPANI-functionalized graphene showed improved electrochemical stability and enhanced electrocatalytic activity.
متن کاملNon-Covalent Derivatives: Cocrystals and Eutectics.
Non-covalent derivatives (NCDs) are formed by incorporating one (or more) coformer molecule(s) into the matrix of a parent molecule via non-covalent forces. These forces can include ionic forces, Van der Waals forces, hydrogen bonding, lipophilic-lipophilic interactions and pi-pi interactions. NCDs, in both cocrystal and eutectic forms, possess properties that are unique to their supramolecular...
متن کاملCovalent functionalization of N-doped graphene by N-alkylation.
Nitrogen doped graphene was modified by N-alkylation using a combination of phase transfer catalysis and microwave irradiation. The resulting derivatives of N-doped graphene were analysed showing that the bandgap of the material varied depending on the alkylation agent used.
متن کاملHighly selective covalent organic functionalization of epitaxial graphene
Graphene functionalization with organics is expected to be an important step for the development of graphene-based materials with tailored electronic properties. However, its high chemical inertness makes difficult a controlled and selective covalent functionalization, and most of the works performed up to the date report electrostatic molecular adsorption or unruly functionalization. We show h...
