“…Polyaniline has been an important member in the ICP family, owing to its easy preparation, excellent environmental stability, various forms, interchangeable oxidation states, electrical and optical properties, and low cost [1][2][3]. It has various potential applications in many high-performance devices such as rechargeable batteries [4], chemical sensors [5], electrochemical and corrosion devices [6,7] organic light emitting diodes (OLEDs) [8], field-effect transistors (OFETs) [9], and solar cells [10][11][12]. The common synthesizing method of conducting polymers is, namely, the chemical oxidative [13] or electrochemical [14] polymerization.…”

Conducting polymer poly(O-toluidine) (POT) doped with dodecyl benzene sulfonic acid was prepared by the chemical polymerization with the help of ammonium persulphate (NH4)2S2O8 as an oxidizing agent. This polymer was blended with different weight ratios (0%, 10%, 15%, 25%, 35%, 45%, 50%) of poly(ethylene oxide) (PEO) to produce nano conducting polyblend POT-DPSA/PEO, prepared by the spin coating method, and deposited on a glass substrate. The surface morphology was studied by scanning electron microscope. The optical properties of a prepared film was studied from the absorbance spectra at wavelengths 300-1100 nm. The analysis of optical measurement data shows the direct transition with the energy gap decreasing from 2.80 eV to 2.25 eV, as the content of PEO increases from 0% to 50%.

“…In such systems PANI is used in the form of chemically obtained powders, although we have recently used electrochemically obtained PANI powders as corrosion inhibitors in commercial alkyd coatings [26]. Moreover, composites of PANI and especially inorganic pigments usually present in conventional coatings were also considered, exhibiting increase of the mechanical and protective properties [40,47,54,57,62].…”

“…Polyaniline is an important member of the intrinsically conductive polymers because of the ease of its preparation, an excellent environmental stability, interchangeable oxidation states, electrical and optical properties, economic costs, [2][3][4] and because they can be used for chemical sensors, 5,6 electromagnetic shielding, 7 electrochemical and corrosion devices. [8][9] Polymerization of a conducting polymer may be performed with chemical 10 or electrochemical 11 methods. Different chemical oxidizing agents such as potassium dichromate, [12][13][14] potassium iodate, 15 hydrogen peroxide, 16 ferric chloride or ammonium persulphate 17 can be used.…”

Chemical oxidative copolymerization of o-phenylenediamine -co-o/p-toluidine at different molar ratios of monomer was performed using potassium dichromate as an oxidant. The resulting copolymers were investigated using Fourier transform infrared spectroscopy (FTIR) and UV-visible spectroscopy. In the copolymer, the intensity of the band at 1005 cm -1 is substantially decreased due to the -CH3 bending vibrations. A hyposochromic shift is observed in UV-visible spectroscopy. The electrical-conductivity values obtained for the o-toluidine copolymers are higher than those for the p-toluidine copolymers. Keywords: o-phenylenediamine, o-toluidine, p-toluidine, conductivity, chemical oxidativeness, FTIRIzvedena je bila kemijska oksidativna kopolimerizacija o-fenilendiamina-co-o/p-toluidina pri razli~nih molarnih razmerjih monomera, z uporabo kalijevega dikromata kot oksidanta. Nastali kopolimeri so bili preiskovani z uporabo infrarde~e spektroskopije s Fourierjevo transformacijo (FTIR) in UV-vidno spektroskopijo. V kopolimeru je intenziteta pasu pri 1005 cm -1 ob~utno zmanj{ana zaradi upogibnih vibracij -CH3. V UV vidnem spektru je opa`en zamik v spektralnem pasu. Vrednosti elektri~ne prevodnosti dobljene pri o-toluidin kopolimerih so vi{je kot pri p-toluidin kopolimerih.
