“…It was due to the presence of surface conjunctions in CNF3 through p-stacking which is in turn due to the increased interaction between PAN and rGOPKS, this effect can facilitate the electron transfer for electrochemical properties. 54 Furthermore, the C1s spectrum (CNF3-Fig. 8b) has two peak binding energies of 284.7 eV and 286.8 eV originating from the C]N and C-N/C-O functional groups, and while the N1s spectrum (CNF3-Fig.…”

“…These synthetic methods give graphene excellent structure and electrochemical properties, such as high specific surface area (~2630 m 2 g −1 ), high electrical conductivity (~10 6 S cm −1 ) at room temperature, stable electrochemical properties, and high theoretical specific capacitance (~550 F g −1 ), which make it a promising material for supercapacitors [45]. Recently, a variety of novel work has been published on graphene and PANI composites, showing new or highly improved properties [46,47,48,49,50,51,52,53,54,55,56,57,58,59,60]. The combination of graphene and PANI on the nanometer scale can induce positive synergistic effects, which can fully utilize the stable EDLC of graphene and the high PC of PANI.…”

Polyaniline has been widely used in high-performance pseudocapacitors, due to its low cost, easy synthesis, and high theoretical specific capacitance. However, the poor mechanical properties of polyaniline restrict its further development. Compared with polyaniline, functionalized carbon materials have excellent physical and chemical properties, such as porous structures, excellent specific surface area, good conductivity, and accessibility to active sites. However, it should not be neglected that the specific capacity of carbon materials is usually unsatisfactory. There is an effective strategy to combine carbon materials with polyaniline by a hybridization approach to achieve a positive synergistic effect. After that, the energy storage performance of carbon/polyaniline hybridization material has been significantly improved, making it a promising and important electrode material for supercapacitors. To date, significant progress has been made in the synthesis of various carbon/polyaniline binary composite electrode materials. In this review, the corresponding properties and applications of polyaniline and carbon hybrid materials in the energy storage field are briefly reviewed. According to the classification of different types of functionalized carbon materials, this article focuses on the recent progress in carbon/polyaniline hybrid materials, and further analyzes their corresponding properties to provide guidance for the design, synthesis, and component optimization for high-performance supercapacitors.

In this work we investigate the behavior of the electrical conductivity of polyaniline when small amounts of graphite nanolayers are added to the polymeric matrix and subsequently suffer an aging process. We observed that graphite tends to increase conductivity whilst aging tends to decrease it. On the other hand, absorption of atmospheric humidity tends to increase conductivity. We show that a mathematical model describes with good agreement the dependence of the conductivity with the aging time.
