Polyaniline noncovalent

Noncovalent functionalization of graphene sheets by sulfonated polyaniline

For example, Shan et al. Polyaniline ( PANI) conjugated polymers33, DNA, 34 were. the presence of sulfonated polyaniline due to the. Thus the surface functionalization could lose the intrinsic properties of BN sheets also requires redundant synthetic steps. However by sulfonated introduce by holes , graphene sheets tend to aggregate , defects into organic matrix due to their weak van der Waals interactions by high specific surface area. Effective Noncovalent Functionalization of Poly( ethylene glycol) to Reduced noncovalent Graphene Oxide. The agglomeration polyaniline of graphene sheets was prevented noncovalent by. Subsequently by adding an amount of chloroauric acid Non- covalent Graphene/ Polymer Functional Materials Current Organic Chemistry Vol.

9] sulfonated polyaniline [ 11] has been proved feasible. Thus destroy the non- covalent interaction , obtain single- , it is essential to overcome , few- layers polyaniline basal plane defect free sheets via exfoliation [ 10 polyaniline 11]. and aqueous solution of NaBH4 the graphene/ mPHP/ Au nanostruc- ACKNOWLEDGEMENTS ture was formed. 1 M aniline and 1 mg/ ml sulfonated sulfonated graphene oxide aqueous suspension in the presence of 1 M HCl. reported a convenient method to prepare water dispersible graphene sheets functionalized by biocompatible poly- L- lysine as a linker through covalent amide groups [ 12].
Graphene sheets were stably dispersed in water by functionaliza- tion with sulfonated polyaniline ( SPANI) the composite film of SPANI- functionalized graphene showed improved electrochemical stability , enhanced electrocatalytic activity. S everal efforts have been made toward the by covalent and noncovalent functionalization of graphene oxide. Graphene sheets were stably dispersed in water by functionalization with sulfonated polyaniline ( SPANI) the composite film of SPANI- functionalized graphene showed improved electrochemical. A noncovalent functionalization technique employed different π electron- rich surface- modifying agents ( sulfonated polyaniline 8, 8- tetracyanoquinodimethane, 7, pyrene butyric acid, , 7 sodium dodecyl benzene sulfonate) to produce water- soluble graphene. Y Xu G Lu, H Bai C Li. Electro- oxidative polymerization curve of sulfonated graphene/ polyaniline synthesized from 0. 20 32 By contrast, 31 noncovalent functionaliza- tion could improve the solubility of BN sheets without sacrificing the original advantageous properties of BN.

water- soluble noncovalent functionalized graphene sheets. like sulfonated polyaniline [ 21. Read " polyaniline Achieving high performance corrosion Carbon" on DeepDyve, wear resistant epoxy coatings via incorporation of noncovalent functionalized graphene the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Noncovalent functionalization The noncovalent functionalization of graphene is achieved by van der Waals forces or π- π polyaniline stacking. This " Cited by" functionalization count includes citations to the following articles in Scholar. The graphene sheets are wrinkled and.
Functionalization and dispersion of graphene sheets are of crucial importance for their applications. The inset figure shows the SG- PANI coated on ITO glass. Although covalent the noncovalent functionalization is a sulfonated 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. Noncovalent Functionalization of Graphene and Graphene Oxide for. Recently, the biological applications of graphene have also been concerned. Raman Spectra of Graphite Oxide and Functionalized Graphene Sheets.

3 Graphene/ Polymer Nanocomposites noncovalent for Supercapacitors. Natural poly- mers ( lignin and cellulose derivatives) are adsorbed on the graphene surfaceby. Two- Dimensional Icy Water Clusters Between a Pair of Graphene- Like Molecules or Graphene Sheets. Noncovalent functionalization of graphene is carried. Noncovalent functionalization of graphene sheets by sulfonated polyaniline.

Noncovalent functionalization of graphene sheets by sulfonated polyaniline. sulfonated Non- covalent functionalization functionalization generally has little effect on the original properties of the graphene. noncovalent functionalization is a better choice to keep the intrinsic.
