“…All these results are in agreement with our previous assumption of a "seeding" induced by DND, able to influence the process of nanofiber nucleation during electrochemical polymerization [9] and indicate a similar seeding effect is active also in the case the chemical polymerization. The explanation of such capability has to take into consideration several aspects.…”

“…Moreover the interactions must assure uniform dispersion and immobilization of the nanofiller in the matrix, in order to prevent particle aggregation. However, under such conditions, the spatial control and dispersion of individual nanoobjects can also be utilized to control the organization of the polymer segments, as we also observed in our previous studies dealing with the use of nanosized diamond as filler of polyaniline systems [9]. In comparison to other CP, polyaniline (PANI) is known for being a polymer easy to synthesize, at low cost and with high yield.…”

“…This polymer can be produced in several oxidation states (leucoemeraldine, emeraldine, pernigraniline), each one characterized by a different structure, with several electrical properties and the ability to be produced by chemical or electrochemical synthesis (Tamburria et al 2011;Maia et al 2000;Sapurina and Stejskal 2010;Ćirić-Marjanović 2013). The formation of conductive structures in the polymer is shown in Fig.…”

The development of polyaniline and graphene oxide composites aims to join the unique properties of each material for aerospace applications. The present paper demonstrates an easy and quick method, compared to the ones found in the literature, to obtain a composite made with polyaniline doped with dodecylbenzenesulfonic acid, a combination commonly called polyaniline, and graphene oxide. Nowadays, the most common studied methods are electrochemistry and in situ chemical polymerization. Differently from these methods, the films were obtained by a physical mixture of equimolar suspension of graphene oxide (4 mg/mL) with 3 concentrations of polyaniline powder: 25; 50 and 75%, being compared to pure graphene oxide and polyaniline. The morphology and structure behavior of all the films were studied, besides the bonding nature between both materials. The films were analyzed by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and differential scanning calorimetry. The apparent interaction between graphene oxide corrugated sheets and polyaniline grains was verified by scanning electron microscopy images. It can be noticed, as the concentration of polyaniline increases, that more polymer was entrapped. To prove the formation of polyaniline/graphene oxide composite, X-ray diffraction and Fourier transform infrared spectroscopy techniques demonstrated the changes on graphene oxide crystallographic plans and on the chemical bonding between polyaniline and graphene oxide, suggesting an interaction between polyaniline and graphene oxide, especially in the composite with 50% polyaniline/50% graphene oxide. Differential scanning calorimetry was used to highlight this effect through the increase in thermal stability. The method of physical mixture was efficient to obtain the polyaniline/ graphene oxide composites.

“…Diamond nanoparticles have been employed as the electrode material for energy storage, such as for electrochemical capacitors [108][109][110][111][112][113]136], lithium batteries [114,115], and dye-sensitive solar cells [116]. For supercapacitors, diamond nanoparticles are always thermally annealed at the temperatures above 1000°C.…”

Macro-sized diamond films have been widely applied as the electrode for electrochemical and electroanalytical applications. Due to the non-uniform doping in diamond, boundary effects, and the varied ratios of graphite to diamond, only averaged electrochemical signals are detected over the full electrode. The studies of diamond electrochemistry at the nanoscale are thus highly required. In this chapter we overview recent progress and achievements about electrochemical properties and applications of diamond nanostructures and nanoparticles. After a brief introduction of the formation of these nanostructures and nanoparticles, electrochemical behavior of diamond nanostructures (e.g., diamond nanotexures, nanowires, networks, etc.) and nanoparticles (undoped, doped nanoparticles) in the presence/ absence of redox probes is summarized. Their electroanalytical (e.g., electrochemical, biochemical sensing, etc.) and electrochemical (e.g., energy storage using capacitors and batteries, electrocatalysis, etc.) applications are shown. Diamond nanoelectrode array is introduced and highlighted as a promising tool to investigate diamond electrochemistry at the nanoscale as well.
