Synthesis of Sulfosalicylic Acid Doped Polyaniline/MultiWalled Carbon Nanotubes Composite Film Modified Electrode and Its Applications

Abstract

Abstract: Abstract： The sulfosalicylic acid (SSA) doped polyaniline/multiwalled carbon nanotubes (PANI/SSA/MWCNTs) composite film modified electrodes were synthesized by electropolymerization. The modified electrode was characterized utilizing the scanning electron microscope (SEM), fourier transform infrared spectroscopy (FTIR) and electrochemical techniques. The results showed that the morphology of the PANI/SSA/MWCNTs modified Pt electrode was more uniform and compact compared with the PANI Pt electrode. The conductive properties improved significantly and there was an increment in the current from 145 μA up to 1.61 mA. The charge injection capacity of the electrode increased by about 12.1 fold. The electrodes showed a high electrocatalytic activity and good linear current response of ascorbic acid (AA) with a sensitivity of 9.09 A/(mol·cm2) and a correlation coefficient of 0.996 0. In addition, this electrode could be used for selective determining AA in the presence of oxalic acid with a large peak separation of about 340 mV.
