Canopy Non- covalent functionalization of graphene with polymers As shown in the aforementioned examples, the covalent functionalization of polymers on graphene- based sheets sheets holds versatile possibility due to the rich surface chemistry of GO/ r- GO. This is apparent from the fact that so far, successful covalent functionalization of this sp 2 canopy planar canopy carbon allotrope has only been reported on surface bound pre- exfoliated non graphene sheets. Non- covalent functionalization solubilization of graphene , single- walled carbon nanotubes ( SWNTs) has been explored in non- polar organic solvents with various electron- donor - acceptor molecules. Non covalent functionalization of graphene sheets by canopy. In by by summary, non- covalent functionalization of graphene sheets by non SPANI makes the SPANI/ r- canopy G soluble in water at high concentration ( 41mgmL1). Second‐ order non Møller– Plesset ( MP2) perturbation theory on a cluster model ( methylamine on pyrene) yields a binding energy of by ≈ 220 meV for the amine– graphene canopy interaction, which is strong. The composite ﬁlm of SPANI/ r- G exhibits high conductivity good electrocatalytic activity stability. to graphene sheets results in the introduction by of a band gap,. The organic covalent functionalization reactions of graphene.
Functionalization of Graphene: Covalent and Non- Covalent. This composite material has potential applications in electrocatalysis and electrochemical sensing.
It has been defined as single- layer, bi- layer and few- layer, depending on the number of layers of graphene sheets present. Similar to CNTs, graphene has been functionalized by covalent and non- covalent means to achieve various applications ( Rao et al. ,, Compton and Nguyen, ). 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.
