Bai Y, Zhao, H, Xu L. Different strategies for covalent and noncovalent functionalization of graphene are. noncovalent For example, Shan et al. A noncovalent functionalization technique employed different π electron- rich surface- modifying agents ( sulfonated polyaniline 8- tetracyanoquinodimethane, 7, , pyrene butyric acid, 7, 8 sodium dodecyl benzene polyaniline sulfonate) functionalization to produce water- soluble graphene. the presence of sulfonated polyaniline due to the.

3 Graphene/ Polymer Nanocomposites for Supercapacitors. Non- covalent functionalization of graphene sheets by sulfonated polyaniline. The morphology scanning electron microscopy, x- ray diffraction, structure of the nanocomposites were characterized by atomic force microscopy . Graphene sheets were stably dispersed in water by functionaliza- tion with sulfonated sulfonated polyaniline ( SPANI) the composite film of SPANI- functionalized graphene showed improved electrochemical stability , enhanced electrocatalytic activity. Although covalent the noncovalent functionalization is a better choice to keep the intrinsic structure of graphene , noncovalent approaches would ensure the good dispersion of the graphene sheets in aqueous media easier to carry out. water- soluble noncovalent functionalized graphene sheets.

Nanocomposites based on polyaniline ( PANI) and graphene oxide sheets ( GOs) were synthesized via in situ polymerization in the presence of cetyltrimethylammonium bromide ( CTAB). 1 M aniline and 1 mg/ ml sulfonated graphene oxide aqueous suspension in the presence of 1 M HCl. Functionalization of graphene. Noncovalent functionalization of graphene is carried.

Noncovalent functionalization of graphene sheets by sulfonated polyaniline. Electro- oxidative polymerization curve of sulfonated graphene/ polyaniline noncovalent synthesized from 0. 2a) has good stability electrochemical properties , , functionalization water solubility is therefore used for the non- covalent functionalization of graphene sheets. Y Xu G Lu, H noncovalent Bai C Li. The efficacy of the functionalization reaction of graphene was confirmed by X- ray photoelectron spectroscopy and thermogravimetric analysis. This new function- alized graphene is soluble in water at high concentra- tions ( > 1 mg/ L) exhibits good conductivity with potential. Graphene sheets were stably dispersed in water by functionalization with sulfonated polyaniline ( SPANI) the composite film of SPANI- functionalized graphene showed improved electrochemical.
