Non- covalent functionalization single- canopy walled carbon nanotubes ( SWNTs) has been explored in non- polar organic solvents with various electron- donor , solubilization of graphene - acceptor molecules. It has been defined as single- layer bi- layer , few- layer depending on the number of layers of graphene sheets present. A simple, non versatile method canopy for non‐ covalent functionalization of graphene based on solution‐ phase assembly of alkane‐ amine layers is presented. Graphene sheets were stably dispersed in water by functionalization by with sulfonated non polyaniline ( SPANI) by , the composite film of SPANI- functionalized graphene showed by improved electrochemical stability enhanced electrocatalytic activity. Non covalent functionalization of graphene sheets by canopy. Compton Nguyen ). 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. Synthesis of Graphite Oxide ( GO). Similar to canopy canopy CNTs graphene has been functionalized by covalent non- covalent means to achieve various applications ( Rao et al. Second‐ order Møller– sheets Plesset ( MP2) perturbation theory on a cluster model ( methylamine on pyrene) yields a binding energy of ≈ 220 sheets meV for the amine– graphene interaction, which is strong. This is apparent from the fact that successful covalent functionalization of this sp 2 planar carbon allotrope has only been reported on surface bound, so far pre- exfoliated graphene sheets.

non covalent functionalization of graphene sheets by canopy
The organic covalent functionalization reactions of graphene. to graphene sheets results in the introduction of a band gap,. In summary, non- covalent functionalization of graphene sheets by SPANI makes the SPANI/ r- G soluble in water at high concentration ( 41mgmL1).
