Detalhes bibliográficos
Resumo:A novel self modification of grafted polymer working electrode with carbon nanotubes was success for fabrication from grafting polymer via gamma irradiation and ferrous ammonium sulfate (FAS) as a catalyst. The electrochemical properties of the self modified grafted polymer with CNT (GPESMCNT) improved performance the working electrode at higher conducting surface was done through using in cyclic voltammetry (CV). The GPESMCNT was characterized by surface analytical methods including AFM and SEM. The characterization of electrocnductivity properties of GPESMCNT was studied in 1M of KCl with different concentration of K3(Fe(CN)6), at different scan rates, temperature, and different concentrations using CV technique. The new GPESMCNT improved performance the working electrode in CV at different techniques such as rotating disc electrode (RDE). also, the nanomaterials in the chain of grafted polymer was enhanced the redox current peaks of Fe(II)/Fe(III) multi times than at commercial working electrodes such as GCE, Pt-electrode, Au-electrode, etc.
