Non covalent functionalization of graphene sheets by canopy. Second‐ order Møller– Plesset ( MP2) perturbation theory on a cluster model ( methylamine on pyrene) yields a binding energy of ≈ 220 meV for the amine– graphene interaction, which is strong.

Non- covalent functionalization solubilization of graphene , single- walled carbon nanotubes ( SWNTs) has non been explored in non- canopy polar organic solvents with canopy various electron- donor - acceptor molecules. Compton Nguyen ). by A simple, versatile method for non‐ covalent functionalization of graphene based on solution‐ phase assembly of alkane‐ amine layers is presented.
This is apparent from the fact that, so far, successful covalent functionalization of this sp 2 planar carbon allotrope has only been reported on surface bound, pre- exfoliated graphene sheets. Non- covalent Functionalization of Graphene Sheets by Sulfonated Polyaniline Hua Bai, Yuxi Xu, Lu Zhao, Chun Li and Gaoquan Shi* Department of Chemistry and the Key Laboratory of Bio- organic Phosphorous Chemistry and Chemical Biology, Tsinghua University, Beijing, 100084, P. Synthesis of Graphite Oxide ( GO). In summary, non- covalent functionalization of graphene sheets by SPANI makes the SPANI/ r- G soluble in water at high concentration ( 41mgmL1).
non covalent functionalization of graphene sheets by canopy
The composite ﬁlm of SPANI/ r- G exhibits high conductivity, good electrocatalytic activity and stability. This composite material has potential applications in electrocatalysis and electrochemical sensing. Non- covalent functionalization of graphene with polymers As shown in the aforementioned examples, the covalent functionalization of polymers on graphene- based sheets holds versatile possibility due to the rich surface chemistry of GO/ r- GO.
