ABSTRACT:The effect of the electrolyte concentration (NaCl aqueous electrolyte) on the dimensional variations of films of polypyrrole doped with dodecylbenzenesulphonate PPy(DBS) on Pt and Au wires was studied. Any parallel reaction that occurs during the redox polymeric reaction that drives the mechanical actuation, as detected from the coulovoltammetric responses, was avoided by using Pt wires as substrate and controlling the potential limits, thus significantly increasing the actuator lifetime. The NaCl concentration of the electrolyte, when studied by cyclic voltammetry or chronoamperometry, has a strong effect on the performance as well. A maximum expansion was achieved in 0.3 M aqueous solution. The consumed oxidation and reduction charges control the fully reversible dimensional variations: PPy(DBS) films are faradaic polymeric motors. Parallel to the faradaic exchange of the cations, osmotic, electrophoretic, and structural changes play an important role for the water exchange and volume change of PPy(DBS).

“…The surface of polyaniline-invertase modified gold electrode obtained was monitored using optical microscopy. Deposition of gold nanoparticles on the surface of polyanilineinvertase modified gold electrode was done using Layer by Layer (LbL) deposition technique [13]. Briefly a Polyaniline-invertase modified gold electrode was immersed into gold nanoparticles solution which was prepared above for 15 min, then dried at room temperature.…”

“…In the last few decades, there has been reported many applications of conducting polymers [18][19][20] . Conducting polymers cast a strong and penetrable surface this behave as a transducer to convert the chemical interaction between the receptor and target analyte into an electric signal [21][22][23][24] . Due to its flexible nature and high order of conductivity, conducting polymer could be grafted on the surface of any conducting and non-conducting support 25,26 .…”

Abstract:We have fabricated graphite, carbon nanotube (CNT) and conducting polymer (polyaniline) based electrochemical sensor for the detection of zinc metal as an environment pollutant. The electrochemical performance of amperometric sensor was tested by cyclic voltammetry, amperometry and linear sweep voltammetry experiments. The developed amperometric sensor displays good electrochemical activity towards the detection of zinc present in the environment. Storage and stability conditions were also tested. Fabricated non-enzymatic amperometric sensor was successfully used for the precise, sensitive and specific detection of zinc metal present as an environment pollutant.
