“…Polyaniline shows exceptional optical, magnetic, chemical, and physical properties, as demonstrated in several experimental and theoretical works (Sajeev et al, 2010;Machado, 2001;Fitrilawati & Tjia, 2001;Vivier, 2000;MacDiarmid, 1997;Geniès et al, 1990;Santos & Brédas, 1989). This -conjugated polymer lends itself to application in several areas, including energy storage, rectification and reversible conductance switching, optical biosensing, electrochromism, protection against corrosion, and use in transistors devices, among others (Chandrasoma et al, 2012;Fan et al, 2011;Nemzera & Epsteina, 2010;Zhao et al, 2009;Bernard et al, 2001;Delongchamp & Hammond, 2001; Bartllet et al, 2000;Vivier, 2000;Guo et al, 1999;Kim et al, 1999;Parente et al, 1992). Polyaniline exhibits enhanced values of the () optical second hyperpolarizability according to experimental measurements (Maciel et al, 1998;Halvorson et al, 1993;Cao et al, 1992;Osaheni et al, 1992).…”

High values of the first (b) and second (g) hyperpolarizabilities were obtained for the halogenated oligomers of the three neutral forms of polyaniline (pernigraniline, emeraldine, and leucoemeraldine). For enhancement of the b and g magnitudes, the t-butyl, t-butoxy, and dimethylamine electron donor groups were introduced into various halogenated oligomers. The effect of the oligomer chain size on the b and g magnitude was also investigated by considering the aniline trimers and hexamers. The highest value of the dynamic b hyperpolarizability (1060 nm) for the second-order harmonic generation (SHG) was found for a pernigraniline hexamer containing fluorine and dimethylamine substituents. The highest g hyperpolarizability magnitudes for the third-order harmonic generation (THG) were observed for all halogenated pernigraniline hexamers containing dimethylamine as a substituent. The AM1/TDHF results show that the halogenated aniline-based molecules are promising candidates for applications in nonlinear optics

“…Furthermore, the classical preparation process of working electrode by mixing PANI, binder and conductive agent, makes the procedures complex, although the binder is not necessary in some preparation process. , The addition of a binder (e.g., polyfluortetraethylene) into the working electrode in classical process impairs the electrical conductivity and increases the internal resistance of the working electrode . Particularly noticeable, the in situ polymerization could complete through one-step reaction and obtain preferable purity products . Several previous works have successfully synthesized PANI nanofibers in situ polymerization, indicating that the obtained PANI nanofibers show better electrochemical properties …”

Polyaniline (PANI) nanofibers-coated graphite electrode is fabricated by microwave-assisted chemical vapor induced in situ polymerization in the presence of ammonium persulfate. The microstructure and electrochemical performance of the as-prepared nanofibers are investigated in detail. The obtained PANI nanofibers at the optimum volume ratio of 4% aniline, with some protuberances on the surface and the diameter from 50 to 100 nm, are coated onto the surface of graphite electrode. The PANI-coated graphite electrodes display the best electrochemical performance in 6 M H2SO4 electrolyte, including a large reversible capacity of 2136 F g(-1) at the current density of 1 A g(-1) and excellent rate capability. In particular, The PANI-coated graphite electrode exhibits a long cycle life by retaining 91% of the initial specific capacitance after 1000 cycles. More importantly, a symmetric supercapacitor was fabricated using PANI-coated graphite electrode, showing maximum energy density and power density of 24 Wh kg(-1) and 6000 W kg(-1), respectively.

We synthesized PANI thin films by chemical oxidative polymerization technique using aniline monomer, oxidizing agent, and dopant acid. The effect of different oxidizing agents such as ammonium dichromate (ADC), chloroauric acid (CAA), and potassium permanganate (PPM) on the properties of PANI was investigated. The as-prepared PANI colloids were thoroughly characterized using a range of characterization techniques. Raman spectra demonstrate that all the intense bands associated to the emeraldine salt form of PANI. Optical absorption spectra revealed that the absorption peaks corresponds to π-π*, polaron and bipolaron transitions of emeraldine salt form of PANI. PL spectra demonstrate that the relative intensity of the peak arises due to the polaron band de-excitation increases for the PANI film synthesized using PPM due to the highest redox oxidation potential. A clear change in the surface morphology was observed for the samples grown with different oxidizing agents. A long fiber-like structure detected with CAA is proposed to be responsible for the development of the highly conducing emeraldine salt of PANI. The PANI sample prepared with CAA not only measured good electrical conductivity but the optical and morphological properties also showed promising characteristics for various device applications.
