“…Its presence in the TX100 liquid spectra suggests the -CH inplane vibration [34]. The band at 806 cm −1 is due to quinoid ring deformation or the 1,4disubstituted ring, confirming para-coupling in the PANI chains [26]. The FTIR spectra of liquid Triton TX100 and PANI synthesized with and without the presence of a nonionic surfactant are shown in Figure 11.…”

Polyaniline (PANI) is a conductive polymer easily converted into a conducting state. However, its limited mechanical properties have generated interest in fabricating PANI composites with other polymeric materials. In this study, a PANI–prevulcanized latex composite film was synthesized and fabricated in two phases following chronological steps. The first phase determined the following optimum parameters for synthesizing nanosized PANI, which were as follows: an initial molar ratio of 1, a stirring speed of 600 rpm, a synthesis temperature of 25 °C, purification via filtration, and washing using dopant acid, acetone, and distilled water. The use of a nonionic surfactant, Triton X-100, at 0.1% concentration favored PANI formation in a smaller particle size of approximately 600 nm and good dispersibility over seven days of observation compared to the use of anionic sodium dodecyl sulfate. Ultraviolet–visible spectroscopy (UV-Vis) showed that the PANI synthesized using a surfactant was in the emeraldine base form, as the washing process tends to decrease the doping level in the PANI backbone. Our scanning electron microscopy analysis showed that the optimized synthesis parameters produced colloidal PANI with an average particle size of 695 nm. This higher aspect ratio explained the higher conductivity of nanosized PANI compared to micron-sized PANI. Following the chronological steps to determine the optimal parameters produced a nanosized PANI powder. The nanosized PANI had higher conductivity than the micron-sized PANI because of its higher aspect ratio. When PANI is synthesized in smaller particle sizes, it has higher conductivity. Atomic force microscopy analysis showed that the current flow is higher across a 5 µm2 scanned area of nanosized PANI because it has a larger surface area. Thus, more sites for the current to flow through were present on the nanosized PANI particles.

“…Besides the carbon, a polymer as support of the electrocatalyst for enhancing the electrocatalytic properties is reported. [30] The conducting polymers such as polypyrrole (PPY), [31,32] polyaniline (PANI), [33][34][35] and polythiophene [36,37] poly (3,4-ethylene dioxythiophene) : poly(styrene sulfonate) [38,39] and others [40] could be prepared either electrochemically or chemically. The chemically prepared polymer has some advantages such as preparation of bulk amounts, which can be used as electrode materials gradually.…”

Nano-Co 3 O 4 was used for electrocatalytic water oxidation due to its promising features of better performance and low cost. An enhanced electrochemical water oxidation performance of the nanoparticles can be achieved by mixing them with other types of highly conductive nano/microstructured materials. Conductive polymers would be one of the candidates to achieve this goal. Here, we report our recently developed nano-Co 3 O 4 and polypyrrole composites for enhanced electrochemical water oxidation. We chose polypyrrole as a support of nano-Co 3 O 4 to obtain highly active sites of nano-Co 3 O 4 with high conductivity. Morphological and chemical characterization of the prepared materials were performed using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). After immobilizing them individually on fluorine doped tin oxide (FTO) substrate, their electrocatalytic properties toward water oxidation were investigated. The optimum composite materials showed significantly higher electrocatalytic properties compared to that of pure nano-Co 3 O 4 and polypyrrole. Electrochemical impedance studies indicated that the composite materials possess significantly less electron transfer resistance toward water oxidation reaction compared to that of only polypyrrole or nano-Co 3 O 4 , while the higher double-layer capacitance and polarization resistance values obtained from fitting of the impedance data represent the faster electrode kinetics in the composite electrocatalyst. Due to the synergetic effect, the optimum nano-Co 3 O 4 and polypyrrole composites could be represent a novel and promising material for water oxidation.

Due to the low cost, and extraordinary physical and chemical properties, attapulgite (ATP) has sparked considerable interest as water remediation materials. Since traditional ATP nanomaterials have inherent limitations in separation and recycle, this paper focuses on designs of recyclable attapulgite composites, which show great potential in practical environmental remediation. First, the advantages of ATP properties are highlighted and discussed in comparison with other one-dimensional materials. Then, three types of strategies are summarized to fabricate recyclable ATP nanocomposites: (1) magnetic attapulgite adsorption materials, (2) millimeter-sized attapulgite-based adsorbents, and (3) filtration membranes/meshes. Additionally, the syntheses, applications, and corresponding mechanisms toward numerous pollutants are included. Finally, challenges and future prospects of fabrications and applications are presented.
