“…Similar to the previously reported graphene/polypyrrole composite materials, they are overlapped with the D-band and G-band of graphene [29]. Since these rGO-PPy respectively [30,31]. The band at 1150 cm -1 is due to the stretching vibration of the sulfonate group in pTS [32].…”

Here we developed a free-standing reduced graphene oxide (rGO)-polypyrrole (PPy) hybrid paper via electropolymerization on a paper-like graphene gel. This flexible hybrid paper displayed a uniform layered structure with PPy coated onto the graphene layers. A high areal mass of 2.7 mg cm−2 could be obtained. It delivered a greatly enhanced areal capacitance of 440 mF cm−2 at 0.5 A g−1, in contrast to that 151∼198.5 mF cm−2 previously reported for graphene paper or polypyrrole-graphene paper. It can retain ∼81% of the initial capacitance at a high current density of 6 A g−1. The combined high flexibility with outstanding electrochemical performance, makes such novel hybrid paper a promising electrode for flexible supercapacitors.

“…In the past, there was a difficulty to make a copolymer of aniline and pyrrole because of synthesis method for each of them [1]- [2]. Now, there are two main ways to synthesize a copolymer of aniline and pyrrole by chemical [3]- [7] or electrochemical [8]- [10]methods. Chemical oxidation process has been checked in previous studies where ammonium peroxydisulfate solution (APS) is used as oxidant [3]- [7].…”

Abstract. The morphology and surface area of the poly(aniline-co-pyrrole) copolymer (PANPY) are important properties which improve the efficiency of the copolymer in various applications. In this investigation, different techniques were employed to produce PANPY in different morphologies. Aniline and pyrrole were used as monomers, and ammonium peroxydisulfate (APS) was used as an oxidizer with uniform molar ratio. Rapid mixing, dropwise mixing, and supercritical carbon dioxide (ScCO 2 ) polymerization techniques were appointed. The chemical structure, crystallinity, porosity, and morphology of the composite were distinguished by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Brunauer, Emmett and Teller (BET) analysis, and transmission electron microscopy (TEM) respectively. The characterization tests indicated that the polyaniline/polypyrrole copolymer was successfully prepared with different morphologies. Based on the obtained TEM, hollow nanospheres were formed using rapid mixing technique with acetic acid that have a diameter of 75 nm and thickness 26 nm approximately. Also, according to the XRD, the produced structures have a semi-crystalline structure. The synthesized copolymer with ScCO 2 -assisted polymerization technique showed improved surface area (38.1 m 2 /g) with HCl as dopant.

“…Compared to pure COP, composites of COP with other materials such as metals are gaining attentions due to unique properties and applications. Blinova et al [19,20], synthesized PANI-silver nanocomposites and reported higher conductivity of the nanocomposites as compared to pure PANI.…”

“…Overall, their work was just a confirmation of the copolymerization, not the structure determination. Stejskal et al [20] and Lim et al [27] reported a copolymer of Poly(Ani-co-Py), and found a nonlinear trend in the conductivities of Poly(Anico-Py) samples, which were synthesized using HCl as dopants. They attributed the decrease in conductivity of the copolymer, with increase in Py, to the shortening effect of PANI chain through the copolymerization or heterodiads formation of Ani with Py rather than to forming Ani blocks.…”

Quantum mechanical calculations are performed to establish the structure of an oligomer of aniline and pyrrole [Poly(Ani-co-Py)], through comparison of experimental and theoretically calculated properties, including conductivity. The copolymer was synthesized through chemical oxidative polymerization and then confirmed from the experimental IR, UV-vis, mass spectra, elemental, XRD, TGA, and SEM analysis. Quantum mechanical calculations are performed at Density Functional Theory (DFT) and Time dependent DFT (TD-DFT) methods for the electronic and spectroscopic properties of the oligomer. A very nice correlation is found between the theory and experiment which consequences the structure of Poly(Ani-co-Py). Poly(Ani-co-Py) is not explored like other conducting polymers; however, by tuning this molecular structure, the electro-active nature of this material can be enhanced adequately.
