“…In general, PANI films containing carbon nanostructures showed improved properties like a lower resistance and higher mechanical stability than pure PANI films. Another CNO-containing composite material was prepared from unmodified or oxidized CNOs and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) [47]. In a very recent study, they reported the non-covalent functionalization of CNOs with poly(4-vinylpyridine- co -styrene) (PVPS) and poly(ethylene glycol)/Polysorbate 20 (PEG/P20) [48].…”

“…After optimization in a follow-up study, the highest specific capacitance for a CNO–PANI composite was measured to be 525 F·g −1 , which renders this composite material interesting for applications in supercapacitor electrodes [46]. Also the CNO/PEDOT:PSS composites, which were previously discussed, showed promising properties for the application as electrode material in supercapacitors, such as a specific capacity of 96 F·g −1 , good cation-exchange properties and a simple synthesis [47]. In a recent study, the same group decorated the surface of CNO with Ni(OH) 2 or NiO as pseudocapacitive redox material and showed that these composites can be promising materials for the development of supercapacitors [61].…”

SummaryThis review focuses on the development of multi-layer fullerenes, known as carbon nano-onions (CNOs). First, it briefly summarizes the most important synthetic pathways for their preparation and their properties and it gives the reader an update over new developments in the recent years. This is followed by a discussion of the published synthetic procedures for CNO functionalization, which are of major importance when elucidating future applications and addressing drawbacks for possible applications, such as poor solubility in common solvents. Finally, it gives an overview over the fields of application, in which CNO materials were successfully implemented.

“…53 For the preparation of the lms a conductive carbon paste was used to solubilize the non-modi-ed and modied CNOs for further modication of the GC surface electrodes. As was previously observed, the capacitive performance of the carbon electrodes depends on their preparation protocol.…”

Small" carbon nano-onions (CNOs) are spherical, ca. 5 nm in diameter, concentric shells of graphitic carbon that can be also described as multi-shelled fullerenes. Given the easy functionalization and high thermal stability of the CNOs produced from nanodiamond, they are the most obvious choice for studying the potential applications of these multi-shelled fullerenes in electrochemical supercapacitors (ES). Since limited accessibility of the carbon surface to electrolyte penetration is observed for carbon nano-onions, performance enhancement was accomplished by modifying the CNO surfaces with pseudocapacitive redox materials: Ni(OH) 2 and NiO. These composites were characterized by TEM, SEM, XRD, TGA-DTG-DTA and Raman spectroscopy. The electrochemical properties of these composites were also investigated. Compared with pristine CNOs (30.6 F g À1 at 5 mV s À1 ), modified CNOs (1225.2 F g À1 for CNOs/Ni(OH) 2 and 290.6 F g À1 for CNOs/NiO, both at 5 mV s À1 ) show improved electrochemical performance, promising for the development of supercapacitors.

“…Although PEDOT has electrical conductivities two or three magnitudes higher than polyaniline, its thermal stability is limited up to 180 °C. To overcome this inconvenience many authors have attempted to dope PEDOT and other conductive polymers with nanostructured clays, silico‐aluminates, metal or metal oxides nanoparticles . Gabaldón et al synthesized PEDOT over halloysite nanotubes (HT).…”

Summary: Printed Electronics is the designation given to a set of new technological routes for the manufacture of electronic devices which are light, discrete, flexible, and capable of folding. These devices require power sources that share these properties. This paper is focused on how to obtain electrically conductive elastomer composites. These elastomeric composite materials are obtained by mechanical mixing of electronic and ionic conductive polymers with commercial grade styrenebutadiene rubbers (SBS). The produced materials had good capacitance, thus performing well as rechargeable batteries. These materials were characterized by scanning electron microscopy (SEM) and electrical conductivity measurements to quantify the abundance and distribution of conductive polymers within the rubbery matrix. Our generated experimental results were used to test the predictive power of two mathematical equations based on Hashin-Shtrikman models and composites theory, respectively. Electrical conductivity vs voltage profiles for these conductive elastomer composites were adequately predicted by these models.
