“…This further supports an inhomogeneous distribution of nanohorns in PANI‐CSA/SWCNH composite films. However, to the best of the authors' knowledge, a value of 6.7 × 10 −2 S cm −1 was measured for PANI‐nanohorn nanocomposites synthesized by aniline polymerization in the presence of nanohorns which is consistent with the values measured on PANI‐CSA/SWCNH films.…”

Thermoelectric materials can convert heat into electricity when a temperature gradient is present. The investigation of conductive polymers such as polyaniline (PANI) and poly(3,4-ethylenedioxythiophene) as active materials for thermoelectric generators in the room temperature range is gaining interest because of several key advantages offered by these materials. The relative ease of solution processing, their mechanical stability and flexibility together with low density and low thermal conductivity make conductive polymers suitable for integration in a thermoelectric generator. Polymers offer remarkably low thermal conductivity values but modest Seebeck coefficient and electrical conductivity. In this work, polymer/inorganic nanocomposites of PANI with carbon particles such as single wall carbon nanohorns (SWCNHs) were prepared via solution mixing of the precursors in order to increase the electrical conductivity by means of polymer matrix/nanohorn electronic junctions. The electrical conductivity and Seebeck coefficient were estimated on PANI/SWCNH films and pressed pellets and through-plane thermal conductivity was determined on films. The thermal stability of PANI/SWCNH composites was evaluated by means of TGA/DSC coupled with residual gas analysis. It was found that a proper concentration of SWCNHs in PANI−(+/−)-camphor-10-sulfonic acid (CSA) film was effective in increasing the electrical conductivity without decreasing the Seebeck coefficient.

“…When PANI-SWCNH hybrids were used as electrodes in supercapacitors, the capacitive current improved considerably with a specific capacity of 168 F·g −1 . Khatua also reported the in situ polymerization of aniline in the presence of SWCNH and acidic medium (HCl) [ 77 ]. The composites showed high electrical conductivity in the order of 6.7 × 10 −2 S cm −1 which indicates the formation of a continuous interconnected conducting network path in the polyaniline/carbon nanohorn (PACN) composites.…”

Abstract:With the growth of the global economy and population, the demand for energy is increasing sharply. The development of environmentally a benign and reliable energy supply is very important and urgent. Single-walled carbon nanohorns (SWCNHs), which have a horn-shaped tip at the top of single-walled nanotube, have emerged as exceptionally promising nanomaterials due to their unique physical and chemical properties since 1999. The high purity and thermal stability, combined with microporosity and mesoporosity, high surface area, internal pore accessibility, and multiform functionalization make SWCNHs promising candidates in many applications, such as environment restoration, gas storage, catalyst support or catalyst, electrochemical biosensors, drug carrier systems, magnetic resonance analysis and so on. The aim of this review is to provide a comprehensive overview of SWCNHs in energy applications, including energy conversion and storage. The commonly adopted method to access SWCNHs, their structural modifications, and their basic properties are included, and the emphasis is on their application in different devices such as fuel cells, dye-sensitized solar cells, supercapacitors, Li-ion batteries, Li-S batteries, hydrogen storage, biofuel cells and so forth. Finally, a perspective on SWCNHs' application in energy is presented. OPEN ACCESSNanomaterials 2015, 5 1733

“…The former peak was assigned to the sp 2 carbon atoms of the graphene sheets, and the latter peak was ascribed to the defects on the CNT walls [39]. As shown in Figure 2c, in the case of AF-MWCNTs, the XPS spectrum showed new peaks occurring at 285.6 and 287.2 eV correspond to carbon in C-NH 2 and >C=O, respectively [40,41]. The presence of these peaks confirms the 4-aminobenzoyl moieties on the side walls of the AF-MWCNTs.…”

“…Since their discovery in the 1950s, conducting polymers have been extensively studied and showed great promise in a variety of applications [1][2][3][4][5][6][7]. Among various conducting polymers, polyaniline (PANI) has attracted much attention due to its ease of synthesis, unique and controllable chemical, electrical properties and long-term stability in air.…”

Abstract. The electrocatalytic oxidation of vitamin C at carbon paste electrode (CPE) modified with amino-functionalized multiwalled carbon nanotube/electroactive polyurea (AF-MWCNT/EPU) composite was investigated. We have synthesized novel electroactive polyurea composites containing MWCNTs functionalized with 4-aminobenzoyl groups by an oxidative coupling polymerization. Ultraviolet-Visible spectra and cyclic voltammetry studies confirmed the occurrence of efficient interaction between AF-MWCNT and EPU graft. Moreover, the electrocatalytic activity of vitamin C oxidation by utilizing aniline containing composites was evaluated, showing that the intrinsic electroactivity of AF-MWCNT/EPU-CPE had great potential application for detection of vitamin C. The detection limit and sensitivity of this sensor was 1.2 µM and 35.3 !A·mM -1 , respectively.
