AB  - Polyaniline (PANI) was electrochemically synthesized on graphite electrode galvanostaticaly from aqueous solution of 0.25 mol dm-3 aniline and 0.5 mol dm-3 p-toluenesulfonic acid. Charge capacity available for the exchange and the total theoretical weight of polyaniline polymerized on graphite electrode was determined. Characterization polianiline electrode was performed by cyclic voltametry in 0.5 mol dm-3 HCl. Based on the PANI electrodes behavior during the cyclization, was tested the possibility of practical application of polyaniline doped p-toluenesulfonic acid as the anode material of secondary electrochemical power sources.

AB  - Electrochemical deposition of polyaniline (PANI) on graphite electrode was performed galvanostaticaly at constant current density in the range of 1.0 - 5.0 mA cm(-2) from aqueous acidic electrolyte containing aniline monomer. Based on ratio of doping/dedoping charge capacities, it was estimated that current density of 2.0 mA cm(-2) was optimal. The structure of the electrochemically synthesized PANI was fibrous, uniform and three dimensional with highly developed surface. Immobilization of glucose oxidise (GOx) was achieved by cross linking via glutaraldehyde and the efficiency of the immobilization was determined spectrophotometrically. Chronoamperometric curves were recorded at different glucose concentrations and used to estimate the apparent Michaelis constant, which was shown to be 0.27 mM. The storage stability of the PANI enzyme electrode was also estimated.

AB  - Polyaniline is probably the most investigated electroconducting polymer. This popularity is a result of its important features: existence of various oxidation states, electrical and optical activity, low cost monomer, red/ox reversibility, environmental stability, ease of both chemical and electrochemical synthesis etc. These unique features are partly inherited from its polymeric origin and partly aroused from its conductivity and could be considered for practical application in: electrochemical systems for energy storage and conversion, electronic devices, electromagnetic and microwave shielding materials, sensors, biosensors and corrosion protection as well. The motivation of application of polyaniline in corrosion protection of metals and alloys is replacement of environmentally hazardous materials, e.g. chromates in coating systems. Up to day, lot of studies on various metals both on iron, steels and non-ferrous metals and alloys were performed. The studies involve investigation on individual polyaniline coatings and polyaniline in coating systems. Owing to variation in experimental procedure (substrate, substrate preparation, coating type, corrosion environment, test method etc..) it is unlikely to propose unique mechanism for corrosion protection of metals in the presence of polyaniline. However, most of the literature is interpreted in terms of general mechanisms of corrosion protection, barrier and anodic protection.
AB  - Polianilin je najproučavaniji elektroprovodni polimer. Ova popularnost polianilina je posledica jedinstvenih svojstava, delom nasleđenih od polimerne prirode, a delom ostvarenih provodljivošću. Najvažnija svojstva polianilina: postojanje više oksidacionih stanja, elektronska provodljivost, optička aktivnost, postojanost u spoljašnjoj sredini, mogućnost hemijske i elektrohemisjke sinteze i niska cena monomera nalaze primenu u mnogim oblstima: elektrohemisjkim sistemima za skladištenje i proizvodnju električne energije, elektronici, za izradu sensorskhih i biosenzorskih elektroda, za izradu antistatičkih i materijala mikrotalasnih i magnetnih štitova i u zaštiti metala i legura od korozije. Primena polianilina u zaštiti od korozije je prvenstveno motivisana potrebom zamene toksičnih materijala iz sistema prevlaka. Postoji dosta literaturnih podataka iz ove oblasti. Ipak, imajući u vidu raznovrsnost metala i legura, korozionih sredina, postupaka pripreme materijala, nanošenja prevlaka i vrsta prevlaka, kao i eksperimentalnih procedura i observacija, praktično je nemoguće uspostaviti jedinstven mehanizam antikorozione zaštite metala u prisustvu polianilina. Najcitiraniji i najpopularniji mehanizmi koji se mogu naći u literaturi obuhvataju barijerni mehanizam i mehanizam anodne zaštite.

AB  - A growing interest in biosensors for use in medical, environmental and food analysis has been recognized. Biosensors are devices that transform chemical information, usually the concentration of a specific sample component, into an analytically useful signal. Their selectivity depends on the characteristics of enzyme and biosensors’ response rate and sensitivity on electroconducting polymer used. Glucose oxidase (GOx) is the most widely used enzyme in the field of biosensors because of its high specificity for a commercially important analyte, high turnover number and high stability. On the other side, among the conducting polyheterocyclic polymers, polypyrolle (PPy) is of particular interest because the relatively low oxidation potential of the monomer enables films to be grown from aqueous solutions that are compatible with most of biological elements. The aim of this study was to investigate the possibility of glucose determination using enzyme electrode obtained by immobilization of GOx into polypyrolle electrochemically polymerised on platinum electrode. Electrochemical synthesis was performed in 0.5 mol dm-3 HCl and 0.2 mol dm-3 pyrolle at constant current density of 2 mA cm-2. Polypyrolle/enzyme electrode was formed by immobilization of glucose oxidase via glutaraldehyde into electrochemically synthesized polypyrolle on platinum electrode. Apparent Michaelis constant was determined and it was found to be 0.045 mmol dm-3, which is much lower than that of free enzyme indicating enhanced enzyme efficiency when it is immobilized into polymer electroconducting matrix. PPy/enzyme electrode lost 5% and 18% of its initial signal after 5 and 20 days, respectively.
