Preparation of polyaniline‐poly(ethylene‐vinyl acetate) film: Resistivity in the ESD range

AbstractFilms of polyaniline (PANI) salt with poly (ethylene‐vinyl acetate) (EVA) with two different PANI salts, PANI‐methane sulfonic acid (PANI‐MSA) and PANI‐p‐toluene sulfonic acid (PANI‐PTSA) are prepared by solution processing technique for electrostatic discharge (ESD) application. PANI‐MSA/PANI‐PTSA salts were synthesized by emulsion polymerization pathway then dispersed the PANI salt in xylene solvent. EVA was dissolved in xylene solvent. Series of PANI salt/EVA films were prepared by mixing a particular amount of PANI dispersion to a fixed amount of EVA solution and evaporated the solvent. PANI‐EVA films were evaluated by tensile strength, elongation at break and surface resistivity measurements. The results of PANI‐MSA/EVA films are compared with the results of PANI‐PTSA/EVA films. Also, PANI‐MSA/EVA and PANI‐PTSA/EVA solutions are coated on different substrates and measured their electrical resistivity for ESD application. Morphological study and thermal behaviors of PANI‐MSA/EVA films are carried through FE‐SEM and TGA respectively. Sphere morphology of EVA changed to swollen sheet like morphology with the addition of PANI, and the spaces between the sheets increased with the increase in PANI content. The surface resistivity of the EVA‐PANI films are found to be in the range of 104–108 Ω sq−1, which is suitable for ESD application.

Effect of BaTiO3 Doping on the Vibrational Properties of PAni

Due to the advantages of material abundance and synthetic simplicity, polyaniline can be used as a high-capacity cathode material. However, its practical application in batteries has been hindered by poor electrochemical utilization and cycling instability. This paper reports the enhancement in the conductivity of the polymer (PAni) using the oxidation polymerization method. After successfully synthesis of PAni the vibrational properties have been analyzed by using FTIR. From experimental data, it has been observed that after doping of BaTiO3 the carriers along the surface enhanced which increases vibration along with the fingerprint reason. The polymers showed less electrical conductivity than polyaniline. Unlike polyaniline, the presence of the nitro group caused higher frequency dependence of electrical conductivity. The FTIR bands at 1492, 1291 and 1147 cm−1 are corresponding to the polyaniline salt.

Polyanilines from spent battery powder and activated carbon: Electrodes for asymmetric supercapacitor cell

AbstractThis work aims to use the electro‐active materials for energy storage application from the waste raw material source, readily and indigenously available materials. Nowadays, the use of waste sources to prepare electro‐active materials for energy storage applications is trending due to their low‐cost, high availability, reduced environmental problems, and so forth. In this direction, Polyaniline (PANI) is prepared using a MnO2 oxidant collected from waste Zn‐C cells. PANI displayed a compact and interconnected granular morphology with a surface area (39 m2 g−1), pore volume (0.19 cm3 g−1), and pore diameter (2.2 nm). Activated carbon (AC) has a surface area (860 m2 g−1), pore volume (199 cm3 g−1), and pore diameter (1.2 nm) is purchased locally. FT‐IR, XRD, and EDAX spectra support the formation of polyaniline salt with a small amount of Mn and Zn. The asymmetric cell is constructed using a PANI as a positive electrode and carbon as negative electrode material. The cell (PANI//AC) shows a high specific capacitance of 157 F g−1 at a current density of 5 mA cm−2. The cell offers a cycle life stability of 5000 cycles with a coulombic efficiency of 93% at a current density of 10 mA cm−2.

Effect of HCl Concentration and Acetone Washing on the Dielectric and Conduction Properties of Polyaniline Salts

Background: In order to know the effect of acid concentration, comparative electrical properties of PANI salt samples prepared in two different media like water, 1M HCl and 2M HCl, have been studied. Methods: To know the effect of acetone washing on the electrical behavior of the polymer, the polymer samples were washed with acetone. The X-ray diffraction pattern shows a crystalline nature of all the prepared PANI salt samples except non-acetone washed PANI salt prepared in 2M HCl. The SEM micrograph suggests a uniform and continuous morphology for PANI salts prepared in 1M HCl, agglomerated granulated structure for PANI salts prepared in 1M HCL, and fiber type structure for PANI salts prepared in 2M HCl. Results: The study showed that the dielectric constant decreases with frequency in the case of all the synthesized polymer samples. The variation of AC conductivity of the synthesized polymer samples with respect to the frequency at room temperature follows the power law. Through the fitting parameters, the DC conductivity was found. Conclusion : The results showed that the polymer sample, which was prepared in water medium and not washed with acetone, had the highest dielectric and conductivity values, whereas for acetone washed samples highest dielectric and electrical conductivity was observed for the sample prepared in 2M HCl.

Anticorrosive polyaniline synthesized using coconut oil as the dispersion medium

The eco-friendly and cost-efficient synthesis of polyaniline (PANI) is one of the perplexing tasks in the research horizons of conducting polymers while keeping the desired properties unaffected. The present work reports an eco-friendly and comparably cost-efficient pathway for the synthesis of corrosion-resistant, thermally stable, and highly soluble PANI salt using coconut oil as a novel dispersion medium. The PANI salt was optimized by varying the reaction parameters, such as concentration of monomer, oxidant, surfactant, and solvent. The UV/Visible spectra indicated absorption peaks in the range of 344–353, 424–433, and 740–779 nm. The FTIR analysis of PANI salt reveals the stretching of the benzenoid and quinoid rings at 1460 and 1559 nm respectively. X-ray diffraction shows peaks on 2Ө at 19° and 25° which are the characteristic peaks of PANI. PANI salt was found to be soluble in several organic solvents such as 2-propanol, n-Methylpyrolidinone (NMP), and highly soluble in chloroform and Dimethyl sulfoxide (DMSO) up to 7.6 and 6.9% respectively. SEM images and TGA analysis of PANI confirmed the porous morphology like cauliflower and quite thermally stable up to 538 °C respectively. The layer of synthesized PANI shows remarkable corrosion inhibiting behavior on the surface of mild steel which reduces the rate of corrosion up to 82%. Hence, boost up the global economy.

Zinc tungstate doped polyaniline as room temperature humidity sensing composite

Zinc Tungstate (ZnWO4) a bi-metal oxide is doped in low concentration to polyaniline (PANI) by ‘In-situ’ chemical polymerization method to form a composite. The FTIR characterization technique is used to confirm the formation of polyaniline salt phase and its composites. X-RD & SEM characterization techniques are used to verify the existence of ZnWO4 in PANI matrix. The temperature dependent conductivity shows an exponential behaviour which is thermally activated; the conductivity of the composites has been enhanced by 10 Ohms when compared with pristine PANI. It is reported that electrical resistance decrease, when the composite matrix are exposed to the wide range of humidity from 20 to 90% RH. The decrease of resistance has been recognized as; the chemically adsorbed water vapour donates the electron to the sensing surface in this composite and also due to capillary condensation.

Nitrogen-containing carbon enriched with tungsten atoms prepared by carbonization of polyaniline

Polyaniline (PANI) salts with tungstosilicic (TSA) and phosphotungstic acids (PTA) were prepared by reprotonation of PANI base. Partial protonation of the precursor base was confirmed by Raman spectroscopy and by conductivity measurements. Conductivity of polyaniline tungstosilicate (PANI-TSA) and polyaniline phosphotungstate (PANI-PTA) after reprotonation measured on compressed pellets was found to be 1 × 10–5 S cm−1 and 4 × 10–6 S cm−1, that is significantly higher compared to conductivity of PANI base (⁓ 10–11 S cm–1). According to thermogravimetric and elemental analyses, the amount of heteropolyacids in the resulting salts was ≈ 20 wt%, which corresponded to ≈ 15 wt% of tungsten. Tungsten- and nitrogen-containing carbon derivatives were obtained by carbonization of the prepared PANI salts without losing their conductivity (⁓10–7 S cm–1). Successful carbonization was confirmed by vibrational spectroscopy. Electron microscopy showed that globular morphology typical for PANI base was not affected by reprotonation and carbonization procedures. Elemental analysis confirmed 25.6 and 17.9 wt% of tungsten, 9.7 and 9.6 wt% of nitrogen in the carbonized PANI-PTA and PANI-TSA, respectively. The prepared carbon derivatives can be potentially useful for electrocatalysis.

Semi-Crystalline Polyaniline with an Enhanced Conductivity Synthesized with a Novel Binary Dopant Sulfonic Acid-Surfactant: Mechanical, Electrical and Shielding Performances of Nylon/PANI Conductive Fabrics at 9.45 GHz

Aniline was doped by a novel binary dopant agent, sulfonic acid-surfactant. Naphthalene disulfonic acid (NDSA) and an anionic surfactant (sodium dodecyl sulfate, SDS) were used to form the binary dopant agent; synthesis of the doped PANI was accomplished by using ammonium peroxydisulfate (APS) as the oxidant via a hybrid microemulsion polymerization at various temperatures (–10, 0, 20, and 40 °C). The synthesized polyaniline (PANI-NDSA-SDS) salts were characterized by Fourier transform infrared, UV-visible and Raman spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), the electrical properties were determined using a four-point probe method, and the mechanical properties of the fabric samples were also studied. The PANI-NDSA-SDS salts showed a semi-crystalline structure with nanostructure morphology. Among the four polyaniline salts, the PANI-NDSA-SDS prepared at 20 °C showed higher values of conductivity and polymerization yield. In this study, this polyaniline salt was used as coating materials for preparation of conductive Nylon fabrics. As a result, the tensile strength increased by 15%, from 27.21 to 31.42 MPa. Higher electrical performance was obtained for the Nylon/polyaniline composites, 128–724 ohm/square; thus, for electromagnetic shielding applications, the conducting polyaniline coated Nylon fabrics can be used as a shield material for the control of electromagnetic interference at 9.45 GHz, the frequency of the instrument used for the measurements. The conducting fabrics showed an electromagnetic interference value between 20.09 and 34.44 dB.

Adsorption of methylene blue onto chitosan–montmorillonite/polyaniline nanocomposite

Eco-friendly adsorbent of chitosan–montmorillonite/polyaniline (CH–Mt/PANI) nanocomposite was synthesized by the intercalation of CH into Mt through ion-exchange process followed by the impregnation of aniline. Then in-situ polymerization of aniline using ammonium peroxydisulfate as an oxidant yielded a conducting polymer, polyaniline, as an additional component. The composite with polyaniline salt was also converted to corresponding CH–Mt/PANI base nanocomposite. The composites were characterized by Fourier transform infrared spectroscopy, X-ray diffractometry, thermal gravimetric analysis and electron microscopy and subsequently used for the removal of methylene blue from aqueous solutions. The composite with polyaniline base proved to be better dye adsorbent than that with polyaniline salt and was therefore investigated in detail. The adsorption of the dye onto CH–Mt/PANI base nanocomposite follows the pseudo second-order kinetics and it is well described by Temkin isotherm model. Moreover, the intraparticle diffusion was found to play a significant role in the adsorption mechanism. The maximum adsorption capacity was estimated to be 111 mg g−1, exceeded the adsorption capacities of the individual precursors.

A comparative study of the effect of organic dopant ions on the electrochemical and chemical synthesis of the conducting polymers polyaniline, poly(o-toluidine) and poly(o-methoxyaniline)

Electroactive polymers such as polyaniline and its derivatives have many potential applications, but the nature of the dopants can have an adverse effect on their properties. Polyaniline (PANI), poly(o-methoxyaniline) (POMA) and poly(o-toluidine) (POT) have been synthesised using appropriate organic acid dopants (2-naphthalenesulfonic acid and 1,5-naphthalenedisulfonic acid) via electrochemical and chemical polymerisation methods, where the later was achieved at pH (1–2) in the presence of ammonium persulfate as an oxidant. The effects of the monomers and organic dopants on the physiochemical properties and morphological surface of the polymers were studied by means of Fourier transform infrared spectroscopy, electrical conductivity measurements, thermogravimetric analysis and scanning electron microscopy (SEM). The above films were also synthesised electrochemically whilst varying conditions such as scan rate, scan number and in aqueous solution of organic acids using cyclic voltammetry techniques. Cyclic voltammetry experiments have been employed to analyse the growth behaviour and electrochemical stability of films in the background electrolytes (monomer-free). It was found that PANI salts displayed higher doping levels and conductivity while POMA and POT salts were found to show lower conductivity and doping levels, respectively. Furthermore the electrochemical response of films was different in the stability and this may be because of the methoxy (–OCH3) and methyl (–CH3) groups located at the ortho position of the aromatic ring structure of the monomers (o-methoxyaniline and o-toluidine). The –OCH3 and–CH3 groups have significant steric effects and can reduce to form long chains of polymers and also decrease conductivity. The SEM showed that the morphologies of the prepared conducting polymers were different, which was associated with the nature and size of the dopant and monomer present in the bath solution.

Synthesis, Electrical Conductivity, and Dielectric Behaviour of Polyaniline Doped with H2SO4; HCl and (HCl + NaNO2) Mixture

Acid doped Polyaniline (PANI) due to their increased electrical conductivity, are considered to be the most promising conducting filler materials. Hence, the present study, reports the synthesis of the PANI followed by acid doping, electrical conductivity and dielectric properties measurements of H2SO4; HCl and (Conc. HCl + NaNO2mixture) doped PANI. In order to know the effect of acetone washing on the electrical properties of acid doped PANI samples, the electrical properties of the non-acetone washed acid doped PANI samples are compared with that of their acetone washed counterparts. The PANI salt was prepared by conventional route using aniline hydrochloride and ammonium persulphate as an oxidant. PANI salt was subjected to 0.5M NaOH to form PANI base, which was further doped separately with H2SO4; HCl and (Conc. HCl + NaNO2mixture) respectively followed by acetone washing. A comparative electrical conductivity study between the acetone washed and unwashed PANI salt and H2SO4, HCl and Conc. HCl + NaNO2 mixture doped PANI were characterized by dielectric and impedance study.

Explanation of the high conductivity of HCl protonated polyaniline films

A very high conductivity of polyaniline (PANI) salts can be achieved but different authors provide different explanations of the conduction mechanism. To clarify the problem, we studied the contribution of each type of charge to the total conductivity. The conductivity (1.9–3.5) S cm-1 was found using ohmic gold contacts on a PANI sample applied to glass. In contrast, the conductivity of 8.0 × 10-7 S cm−1 was determined from the volt-ampere characteristic measured on the Au/PANI/Si/In structure in a sandwich configuration. The impedance spectra show that in this structure only polarons and holes participate in the charge transfer while ions only cause sample polarization. Conductivity of 3 × 10-7 S cm−1 caused by ions was determined from the dielectric spectra. Since the sum of all contributions is very low compared to the measured total conductivity, a new mechanism of conductivity is proposed that explains the importance of hydrogen and chlorine molecules for charge transfer.

Kinetic Study of the Effect of the Micellar Concentration of Sodium Dodecyl Sulfate on the Spectroscopic, Morphological and Electrical Characteristics of a Polyaniline Prepared by a Hybrid Micro-Nanoemulsion Bi-Micellar Polymerization Technique

In the present work a study of the micro-nanoemulsion polymerization of aniline (ANI) was undertaken by employing two kinds of micelles as binary dopants, one type based on one of three sulfonic acids, dodecyl benzene sulfonic acid (DBSA), naphthalene-disulfonic acid (NDSA) or para-toluene sulfonic acid (TSA)), and the other based on an added surfactant (sodium dodecyl sulfate (SDS)). The effects of the important parameters, SDS concentration, sulfonic acid nature and temperature, were studied. The resulting polyaniline salts were characterized by attenuated total reflectance-Fourier transform infrared (ATR-FTIR), Raman and X-ray fluorescence (XRF) spectroscopy, scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and by a standard electrical resistance four-probe method. The SDS concentration had the predominant role in the doping level, thereby affecting the resultant conductivity. The present investigation revealed that the key parameters, SDS concentration, temperature and sulfur content, in the final product were influential in determining the PANI properties. The oxidation degree increased with a decrease in temperature of polymerization. It was found that the polymerization yield and electrical conductivity of the polyaniline salts PANI-NDSA-SDS and PANI-DBSA-SDS prepared with the critical micelle concentration (CMC) had the highest values and the polymer became thermally more stable. The highest electrical conductivity value obtained was 92.25 S/cm for PANI-NDSA-SDS prepared at 20 °C with the CMC of the SDS.

Synthesis of novel fluorescent molecule and its polymeric form with aniline as fluorescent and supercapacitor electrode materials

AbstractIn this study, a fluorescent material, 2‐naphthyl‐4‐amino benzoate, is synthesized by the esterification of 4‐aminobenzoic acid with 2‐naphthol. This molecule is used in the bulk polymerization of aniline, which results in the formation of poly(aniline‐2‐naphthyl‐4‐aminobenzoate). For comparison, polyaniline and also poly(aniline‐4‐aminobenzoic acid) salts are prepared via bulk polymerization. Formation and properties of these polymeric materials are evaluated by Fourier‐transform infrared (FT‐IR), 13C nuclear magnetic resonance, matrix‐assisted laser desorption ionization, UV‐Vis, Fluorescence, X‐ray diffraction (XRD), Field emission‐scanning electron microscopy (FE‐SEM), Differential scanning calorimetry (DSC), thermogravimetric analysis, electrical resistance and electrochemical techniques. P(ANI‐2NA4ABA) is obtained in nanofiber morphology in 106 wt% yield with respect to the amount of aniline used with comparable conductivity of conventional polyaniline salts. This polymer salt is stable up to 220°C and indicates melting at 146°C on heating and crystal formation at 128°C on cooling. This polymer shows higher wavelength fluorescence compared to the conventional polyaniline salts. This polymer is used as an electrode material without binder, which shows a specific capacitance of 360 F g−1 at 0.25 A g−1.

Tunable electrochemical activity of polyaniline salt by doping anion exchange

The exchange of mobile anion of chemically synthesized polyaniline with counter anions of electrolyte solutions is studied by using cyclic voltammetry (CV). The synthesized polyaniline (PANI) doped with sulfuric acid (H2SO4) and dodecyl benzenesulfonic acid (DBSA) is soluble in a wide range of organic solvents which makes it appealing for further processability. The exchange of dopant anions (of H2SO4 and DBSA) with a variety of counter anion has been inspected by electrochemical cycling in aqueous sodium sulfate (Na2SO4), sodium perchlorate (NaClO4), and sodium hydroxide (NaOH) solution. The CV measurements have revealed that PANI remains redox active at higher scan rate and there is exchange of dopant anion with SO42- and ClO41- of electrolytes. In NaOH solution, the emeraldine salt form of PANI is transformed into emeraldine base due to deintercalation of the anion form polymer matrix. The results indicate a significant change in electrochemical conductance and behavior of PANI in each electrolyte. Furthermore, the polymer film displayed a high specific capacitance value of 588 F/g in 1.0 M NaClO4 solution in the optimized potential window of -0.2 V to 0.9 V at 20 mV/s.

Formation of PANI-PVA salt via H-bonding between PVA and PANI: Aqueous coating for electrostatic discharge, sensor and corrosion applications

This work aims to make environmentally friendly coating consists of an aqueous dispersion of conducting polyaniline (PANI) salt containing H2SO4 and PVA dopants in polyvinyl alcohol (PVA) for electrostatic discharge, sensor and corrosion applications. Aniline is oxidized by ammonium persulfate to PANI-sulfate salt (PANI-SA) without using any protic acids, wherein, sulfuric acid generated from ammonium persulfate during the oxidation of aniline gets doped on to PANI system. The results of PANI-SA are compared with (i) PANI-H2SO4 salt prepared in presence of sulfuric acid in the aniline polymerization and (ii) PANI salt containing dopants of H2SO4 and PVA, (PANI-SA-PVA), prepared with polymeric alcohol, PVA, instead of hazardous sulfuric acid, in the polymerization of aniline. Yield, conductivity, density, diffraction pattern, morphology and thermal properties of PANI-SA are more or less similar to that of the PANI-SA-PVA system. However, yield and conductivity of PANI-H2SO4 are higher than that of PANI-SA-PVA due to the increase of oxidizing efficiency by H2SO4. These three salts, PANI-SA, PANI-H2SO4 and PANI-SA-PVA are dissolved in aqueous PVA. These dispersions are coated on (i) glass slide to find the hydrophilic nature (ii) transparent polyethylene terephthalate film for ESD application, (iii) ceramic tube for sensing ammonia gas, and (iv) stainless steel plate for corrosion study. Among the three PANI salts, PANI-SA-PVA dispersed in PVA shows better performance.

Structural Characterization of Magnetite and its Influence on the Formation of Composites with Polyaniline

In this paper, we present a simple and inexpensive method for synthesizing conductive polyaniline and magnetite composites. Firstly, the magnetite was synthesized by precipitation in basic medium from FeCl 3 , and the Rietveld refinement confirmed the spinel structure. Different amounts of magnetite were used in the in situ synthesis of Pani-Fe3O4 composites to determine the influence, resulting in the following materials: Pani-Fe 3 O 4 (1) with 0.06 g and Pani-Fe 3 O 4 (2) with 0.24 g. The x-ray diffractogram demonstrates that interaction occurs between the polyaniline chains and the magnetite particles in the composites. Infrared and ultraviolet-visible vibrational spectra indicate that the composites are in the state of oxidation polyaniline salt emerald, which is the conductive form of greatest interest. Scanning electron microscopy images show that composites have particles with no definite geometry in the form of clusters, and the best homogeneity was achieved in the composite with the highest amount of magnetite. Evidence indicates that Pani-Fe 3 O 4 (2) material with 0.24 g of magnetite to be incorporated in polyaniline synthesis may have more technologically interesting properties, but further studies will be needed for confirmation.

EFFECT OF PRIMARY DOPANTS ON THE CONDUCTIVITY OF POLYANILINE SYNTHESIZED BY ELECTROCHEMICAL POLYMERIZATION

Polyaniline salts were synthesized at room temperature (300 C) by electrochemical oxidation using primary dopants such as HCL, HNO3, H2SO4 and CH3COOH. All the synthesized PANI have resulted in emeraldine salt form as indicated by dark green colour of the salts. Various characterization techniques employed were UV-Visible spectroscopy, FT-IR and Cyclic voltammetry studies. All these techniques confirm the various properties of PANI. The characteristic peaks in the UV-Visible spectra of the samples indicate that effective doping has occurred in the synthesized polymer polymers. Quinoid and benzenoid bands at 1553-1596 cm-1 and 1437 – 1496 cm-1 respectively were observed in all the samples. The band gaps for all the samples were obtained using the absorption spectra and Stern relation. PANI-H2SO4 had the least band gap whereas PANI-CH3COOH had the highest band gap. The voltammograph showed the various oxidation states during the electrochemical deposition at a potential of 0.8 V. Four probe Method was used to study the conductivity of both thin films deposited on ITO slides. The conductivity values for PANI-H2SO4 were found to be 3.424 S.cm−1 for thin film. By comparing the four samples’ π - π* transition, from the strongest to the weakest were in the order: , PANI-H2SO4 followed by PANI-HCl then PANI-HNO3 and the weakest been PANI-CH3COOH. This suggests that polaron charge carriers are responsible for the high conductivity in H2SO4 doped PANI.

Hybrid material of polyaniline incorporated industrial waste of fly ash to enhance the electrode performance of polyaniline in supercapacitor application

The existing high market potential for supercapacitors in electric vehicles created enthusiasm for the development of safer and high-performance supercapacitor gadgets. The ongoing examination endeavors on electrochemical power sources are composed toward achieving high-explicit energy, high-explicit power, long-cycle life, and so forth, at a realistic cost. In this work, low-cost hybrid material of polyaniline-sulfate salt and ash from the bituminous coal is synthesized via in situ polymerization of aniline. The formation of hybrid in this polymerization process was confirmed from FTIR, XRD, EDAX, and TGA. Thus, prepared polyaniline-sulfate●ash (PANI-ash) hybrid is taken as electro-active material for the construction of supercapacitor cell in a symmetric configuration in 1 M H2SO4 electrolyte. PANI-ash, wherein ash prepared at 600 oC of bituminous coal, gave higher electrochemical performance compared to its individual components of PANI and ash materials. Initial specific capacitance observed for the samples of PANI, PANI-A400, and PANI-A600 are 155, 328, and 363 F g−1, respectively. PANI-A600 symmetric cell system subjected to a higher current density of 0.75 A g−1 for 10,000 cycles. Remaining in specific capacitance values of polyaniline salts at 10,000 CD cycles is found to be 70 %, and further at 35,000 cycles, it shows 43% retention of specific capacitance.

Synthesis of homo/3‐ and 4‐armed hydrophilic glycopolymers: To promote aniline to polyaniline‐glycopolymers for fluorescence, electro active material, and electrostatic discharge applications

ABSTRACTPreparation of electrically conducting polymer film with homogeneity is very important work for electrical and electronic applications. In order to make homogenous conductive polyaniline film, we selected water soluble glycopolymer (GP), as dopant for polyaniline. Pendant carbohydrates water soluble glycopolymer architectures, such as, homo, 3 and 4 multi‐armed polymers were prepared from methacryl‐2,3,4,6‐tetra‐O‐acetyl‐D‐glucopyranoside (MTAGP) monomer and EBrIB and 3‐ and 4‐aremed initiators via ATRP polymerization followed by deacetylation process. This water soluble glycopolymer was used as dopant for polyaniline salt via the chemical oxidative emulsion polymerization of aniline using glycopolymer and surfactant by ammonium persulfate oxidant. Sulfate and dodecylhydrogen sulfate (DHS) groups are doped on polyaniline system via protonating H+, whereas, glycopolymer involves on polyaniline through hydrogen bonding (PANI‐DHS‐SA‐GP). Coated film of PANI‐DHS‐SA‐GP salt showed resistance in ESD range. PANI‐DHS‐SA‐GP showed fluorescence and Hydrophilicity. Electrochemical performance of PANI‐DHS‐SA‐GP as electrode material in supercapacitor cell was found from charge–discharge measurement. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
