The agglomeration of graphene sheets was prevented by. 2a) has good sheets stability water solubility, electrochemical properties , is therefore used for the non- covalent functionalization of graphene sheets. Noncovalent functionalization of graphene sheets by sulfonated polyaniline. Thus the surface functionalization could lose the intrinsic properties of BN sheets sulfonated sheets also requires redundant synthetic steps. This new functionalized graphene is soluble in water at high concentrations ( > polyaniline 1mg/ L) exhibits good conductivity with potential application sulfonated in the field of. The inset figure shows the SG- PANI coated on ITO glass. 1 M aniline and 1 mg/ ml sulfonated graphene oxide aqueous suspension in the presence of 1 M HCl. Highly dispersed noncovalent polyaniline wrapped with GO can increase both catalytic regions of polyaniline conductivity thus favouring the enhancement of photocatalytic activity.

Graphene sheets were stably dispersed in water by functionalization with sulfonated polyaniline ( SPANI) the composite film of SPANI- functionalized graphene showed improved electrochemical.

Sulfonated sheets

To produce a stable aqueous solution of graphene, stabilizers, aqueous dyes, and peptides have usually been used to modify graphene via covalent or noncovalent functionalization. Some water- soluble polymers, like polyvinylpyrrolidone [ 17 ], polyacrylic acid [ 18 ], polyvinyl acetate [ 19 ] and polyglycerol [ 20 ], have also been considered.
