In this research aniline polymerization conditions were optimized in presence of pre-treated polyester textile to achieve as high electrical conductivity as 100 S/Cm. Alkaline activation of the polyester textile was followed by immersion in to aqueous acidic solution of aniline monomer. Then the oxidant solution was used to initiate the polymerization. Finally, the prepared product was washed and dried prior to ant test. Functional groups were studied by Fourie-transformed infrared spectrometry (FTIR) from the surface of the polyaniline coated textile. Also, morphological structure of synthesized conductive polyaniline was studied by scanning electron microscopy (SEM).

Conductive Polyaniline

AbstractThis study explored the preparation of conductive polyaniline-iron oxide (PANI-Fe2O3) that served as the electrical signal transducer, to convert the electrochemical interactions between the biotinylated-goat-anti-mouse IgG (b-IgG) and bovine serum albumin (BSA) into a measurable resistance signal. In this study, PANI was synthesized through the oxidative polymerization of aniline monomer (AM) in the presence of ammonium persulfate (APS) as the oxidizing agent. Concentration effects of AM and volume ratios of AM:APS were evaluated so as to obtain higher conductivity performance in an electrochemical sensing application. The synthesized PANI composites were analyzed through conductivity measurement. The conductive PANI-Fe2O3-GA-b-IgG bio-conjugates was then interacted with BSA, relays the antigen-antibody binding as a measured electrical detection in an assembled pulse-mode electrochemical biosensor. In present work, 0.2 m of AM with 1:3 volume ratio of AM:APS has contributed to the optimal ionic conductivity property of PANI, with excellent electrochemical sensing performance recorded at 3.538±0.067 mΩ.

Afterwhich, the polyaniline was polymerized on the grafted silane aniline molecules using oxidative polymerization. The FTIR spectra showed vibrational peaks associated with the silane aniline molecules and grafted polyaniline. The sampled soaked in silane aniline coupling agent showed FTIR peaks associated with grafted silane aniline. The sample soaked for one minute showed FTIR peaks associated with ortho-coupled aniline units that is formed during the start of aniline polymerization.

Carbon Dioxide Co2

A nanocomposite of cross-linked bacterial cellulose–amino graphene/polyaniline (CLBC-AmG/PANI) was synthesized by covalent interaction of amino-functionalized graphene (AmG) AmG and bacterial cellulose (BC) via one step esterification, and then the aniline monomer was grown on the surface of CLBC-AmG through in situ chemical polymerization. The morphological structure and properties of the samples were characterized by using scanning electron microscopy (SEM), and thermal gravimetric analyzer (TGA). The CLBC-AmG/PANI showed good electrical-resistance response toward carbon dioxide (CO2) at room temperature, compared to the BC/PANI nanopaper composites. The CLBC-AmG/PANI sensor possesses high sensitivity and fast response characteristics over CO2 concentrations ranging from 50 to 2000 ppm. This process presents an extremely suitable candidate for developing novel nanomaterials sensors owing to easy fabrication and efficient sensing performance.

A new class of conductive metal-organic framework (MOF), polyaniline- aluminum succinate (PANI@Al-SA) nanocomposite was prepared by oxidative polymerization of aniline monomer using potassium persulfate as an oxidant. Several analytical techniques such as FTIR, FE-SEM, EDX, XRD, XPS and TGA-DTA were utilized to characterize the obtained MOFs nanocomposite. DC electrical conductivity of polymer-MOFs was determined by four probe method. A bare glassy carbon electrode (GCE) was modified by nafion/PANI@Al-SA, and examined for Zn (II) ion detection. Modified electrode showed improved efficiency by 91.9%. The modified electrode (PANI@Al-SA/nafion/GCE) exhibited good catalytic property and highly selectivity towards Zn(II) ion. A linear dynamic range of 2.8–228.6 µM was obtained with detection limit of LOD 0.59 µM and excellent sensitivity of 7.14 µA µM−1 cm−2. The designed procedure for Zn (II) ion detection in real sample exhibited good stability in terms of repeatability, reproducibility and not affected by likely interferents. Therefore, the developed procedure is promising for quantification of Zn(II) ion in real samples.

In this paper polyester fabrics were pretreated with alkaline solution to improve the ability for the fabric surface to bond with polypyrrole (PPy) coating layer. In situ chemical oxidative polymerization of pyrrole monomer was performed on alkali treated polyester fabrics. Then the fabrics were characterized by FTIR and XRD analysis. The tensile properties of the yarns in both warp and weft directions were measured after alkali treatment and PPy coating processes. The abrasion resistance test was performed on PPy coated fabrics with and without alkali treatment. The surface electrical resistivity of PPy coated fabrics were searched. The electromagnetic shielding effectiveness (EMSE) properties of fabrics in terms of reflection, absorption and transmission behaviors were also investigated. A significant EMSE value increase (about 27%) was obtained with alkali treatment.

In the present work, nanocomposites of polyaniline (PANI) and layered α-Zr(HPO4)2˙H2O (α-ZrP) were prepared using two different approaches: (i) the in situ aniline polymerization in the presence of the layered inorganic material and (ii) the layer-by-layer (LBL) assembly using an aqueous solution of the polycation emeraldine salt (ES-PANI) and a dispersion of exfoliated negative slabs of α-ZrP. These materials were characterized spectroscopically using mainly resonance Raman scattering at four exciting radiations and electronic absorption in the UV-VIS-NIR region. Structural and textural characterizations were carried out using powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The polymer obtained by the in situ aniline polymerization is located primarily in the external surface of the inorganic material although aniline monomers were intercalated between α-ZrP interlayer regions before oxidative polymerization. Through resonance Raman spectroscopy, it was observed that the formed polymer has semiquinone units (ES-PANI) and also azo bonds (—N=N—), showing that this method results in a polymer with a different structure from the usual “head-to-tail” ES-PANI. The LBL assembly of pre-formed ES-PANI and exfoliated α-ZrP particles produces homogeneous films with reproducible deposition from layer to layer, up to 20 bilayers. Resonance Raman (λ0 = 632.8 nm) spectrum of PANI/ZrP LBL film shows an enhancement in the intensity of the polaronic band at 1333 cm–1 (νC—N˙+) and the decrease of the band intensity at 1485 cm–1 compared to bulk ES-PANI. Its UV-VIS-NIR spectrum presents an absorption tail in the NIR region assigned to delocalized free charge carrier. These spectroscopic features are characteristic of highly conductive secondary doped PANI suggesting that polymeric chains in PANI/ZrP LBL film have a more extended conformation than in bulk ES-PANI.

AbstractIt is a novel approach to the synthesize Poly(aniline) / V2O5 nano composite by free radical polymerization method under different experimental conditions such as variation in time, temperature and concentration of aniline and initiator. It was indicated that V2O5 itself could catalyze the oxidative polymerization of aniline. This can be attributed to the internal doping effect, which introduced flexibility to the rigid PANI backbone. TGA counseled the thermal stability of PANI. Through FTIR study, the structure of PANI was established. Comparison of polymerized aniline composite with two different initiators was done.

Multi morphology of polyaniline (PANI), nanotubes, micrograins, solid and hollow spheres, were synthesized by aqueous oxidative polymerization of aniline in the presence of sodium hydroxide (NaOH), which was proposed as an alkali-guided method by the authors. By changing the molar ratio of aniline monomer to alkali, with a constant pH, the morphology can be controlled from nanotubes to micrograins, to solid spheres and to hollow spheres which were proved by SEM and TEM. The backbone structure was characterized by UV-VIS, FTIR and XRD.
