“…Strong bands at 3410-3420 cm -1 are due to N-H stretching in PPy and to O-H stretching in water [17]. Thus, these characteristic bands of PPy for both Alq 3 /PPy composites and PPy are nearly identical, this revealed that there was interaction between Alq 3 and PPy instead of a simple blend of the two polymers [7,18]. We do not observe the absorptions of Alq 3 in Alq 3 /PPy composites may be that Alq 3 has been wrapped in polypyrrole.…”

In this paper, 8-hydroxyquinoline aluminum/polypyrrole (Alq 3 /PPy) core-shell composites were prepared via in situ chemical oxidative polymerization with ammonium persulfate (APS) as oxidizer and hydrochloric acid (HCl) as dopant. The structure and properties of PPy, Alq 3 and Alq 3 /PPy composites have been studied by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and thermogravimetric analysis. The electrical conductivity of Alq 3 /PPy composites were evaluated using ohmmeter. It is found that the Alq 3 /PPy composites is successfully synthesized via in situ oxidative polymerization. The results of thermogravimetric analysis showed that relatively good thermal stability of Alq 3 /PPy composites. Furthermore, the probable formation mechanism of Alq 3 /PPy core-shell structure composites were also proposed on the basis of the experimental results.

“…The third category is also pseudo-capacitor based on faradic reactions, but the electrode materials are electronically conducting polymers [36], or their composites such as polypyrrole (PPy) [37,38], polyaniline (PANi) [39,40], poly(3,4-ethylenedioxythiophene) (PEDOT) [41], and so on. This type of conducting polymers has a relatively high conductivity, and a relatively low cost compared to carbon-based electrode materials [42].…”

Electrochemical capacitors, which can store large amount of electrical energy with the capacitance of thousands of Farads, have recently been attracting enormous interest and attention. Carbon nanostructures such as carbon nanotubes and graphene are considered as the potentially revolutionary energy storage materials due to their excellent properties. This paper is focused on the application of carbon nanostructures in electrochemical capacitors, giving an overview regarding the basic mechanism, design, fabrication and achievement of latest research progresses for electrochemical capacitors based on carbon nanotubes, graphene and their composites. Their current challenges and future prospects are also discussed.

“…Among ICPs, polypyrrole (PPy) is a particularly promising material because of its high electrical conductivity, chemical and environmental stability in the oxidized state, low ionization potential, electrorheological properties, electrochromic effect and relatively easy of synthesis [1][2][3][4][5][6]. In fact, PPy can be potentially used in new advanced technology areas, including electronic and optoelectronic nanodevices [7], sensors [8][9][10][11][12][13], supercapacitors [14,15], energy storage devices [1,7,16], surface coatings for corrosion protection [17], electromagnetic shielding applications [18][19][20], smart textiles [21,22] and even in medical applications [4,[23][24][25][26]. However, the poor mechanical performances and the difficult processability (insolubility and infusibility) [2,3,19,20,27,28] have hampered the use of PPy for technological applications.…”

Abstract. This work describes the production of electrically conductive nanocomposites based on thermoplastic polyurethane (TPU) filled with montmorillonite-dodecylbenzenesulfonic acid-doped polypyrrole (Mt-PPy.DBSA) prepared by melt blending in an internal mixer. The electrical conductivity, morphology as well as the rheological properties of TPU/MtPPy.DBSA nanocomposites were evaluated and compared with those of TPU nanocomposites containing different conductive fillers, such as polypyrrole doped with hydrochloride acid (PPy.Cl) or dodecylbenzenesulfonic acid (PPy.DBSA) or montmorillonite-hydrochloride acid-doped polypyrrole (Mt-PPy.Cl), prepared with the same procedure. The TPU/MtPPy.DBSA nanocomposites display a very sharp insulator-conductor transition and the electrical percolation threshold was about 10 wt% of Mt-PPy.DBSA, which was significantly lower than those found for TPU/Mt-PPy.Cl, TPU/PPy.Cl and TPU/PPy.DBSA. Morphological analysis highlights that Mt-PPy.DBSA filler was better distributed and dispersed in the TPU matrix, forming a denser conductive network when compared to Mt-PPy.Cl, PPy.Cl and PPy.DBSA fillers. This morphology can be attributed to the higher site-specific interaction between TPU matrix and Mt-PPy.DBSA. The present study demonstrated the potential use of Mt-PPy.DBSA as new promising conductive nanofiller to produce highly conductive polymer nanocomposites with functional properties.
