“…However, the use of expensive conducting nanoparticles increases the cost of final products and may deteriorate some other desired properties of polymeric matrices, that is, flexibility and uniformity. 7 Intrinsically conducting polymers (ICPs), such as polyaniline (PANi), polypyrrole (PPy), and polythiophene (PT), have attracted the interest of scientists and industry because of their high electrical conductivity and good environmental stability. 8 Nonetheless, conducting polymers often suffer from poor mechanical properties and environmental stability which prevent their widespread applications.…”

Electrically conducting polyaniline/multiwalled carbon nanotubes (PANi/MWCNTs) nanocomposites were successfully synthesized via chemical oxidative polymerization. For this purpose, PANi was first prepared in an aqueous acidic medium, hydrochloric acid (HCl), at various temperatures to determine the proper polymerization temperature and to prepare the polymer with the highest electrical conductivity. For nanocomposite preparation, the polymerization of aniline (ANi) was carried out in the presence of various amounts of MWCNTs dispersed using a proper surfactant. The effect of HCl and MWCNT contents on the conductivity of the resultant composites was investigated. The results showed that the conductivity was monotonically increased with increasing the MWCNT and HCl levels. In addition, the effect of anionic and cationic surfactant type, sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB), on the conductivity and morphology of the resulting nanocomposites, was studied. Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, two- and four-point resistivity measuring methods, and field emission scanning electron microscopy (FESEM) were used to characterize the neat PANi and PANi/MWCNT nanocomposites. The conductivity variation of the conducting polymers versus elapsed time was investigated to determine the intensity and dominant aging mechanism. Electromagnetic shielding properties of the conducting nanocomposites were also studied. The results indicated that the nanocomposite with the highest MWCNTs level absorbed more than 83% of the incident electromagnetic waves.

“…Due to the unique physical and chemical properties and their being easy to synthesize and obtain, MWCNTs are broadly applied for the preparation of various composite materials [2,3]. The electrical conductivity, thermal stability and mechanical strength of the composite, which included nanotubes and conjugated polymers, has been improved since plenty of work has been devoted to the development of see-through materials [4]. Especially after the combination of MWCNTs and conductive polymer PANI and other carbon nanomaterials, it can be used in supercapacitors [5] and effective adsorbents [6].…”

Based on various carbon nano materials, the ternary composite functionalized carbon nanotubes (FMWCNTs) @ carbon quantum dots (CQDs) @ polyaniline (PANI) was prepared by in-situ polymerization and hydrothermal method. The carbon-based material was made into an electrode sheet. The morphology and microscopic nanostructures were characterized by FTIR, field emission scanning electron microscopy and field emission transmission electron microscopy. Cyclic voltammetry and the galvanostatic charge discharge method was adapted to study the electrochemical properties of these active materials. Our results showed that the specific capacitance of FMWCNTs @ CQDs @ PANI was as high as 534 F/g, while it was 362 F/g, 319 F/g and 279 F/g for PANI @ FMWCNTs, PANI @ CQDs and polyaniline. This means that the specific capacitance of FMWCNTs @ CQDs @ PANI is increased by 47.5%, 67.4% and 91.4% comparing with the capacitance of PANI @ FMWCNTs, PANI @ CQDs and polyaniline, respectively. Moreover, the specific capacitance retention rate of the ternary active electrode after 1000 times of constant current charge and discharge cycle reached 86%, while it was 60% for PANI @ FMWCNTs, 72% for PANI @ CQDs and 65% for polyaniline.

Herein, we present the results of sulfonated polyaniline (SPANI) and sulfonated poly(ether sulfone) (SPES) composite polymer electrolyte membranes. The membranes are established for high-temperature proton conductivity and methanol permeability to render their applicability. Composite membranes have been prepared by modifying the SPES matrix with different concentrations of SPANI (e.g., 1, 2, 5, 10, and 20 wt %). Structural and thermomechanical characterizations have been performed using the transmission electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and dynamic mechanical analyzer techniques. Physicochemical and electrochemical properties have been evaluated by water uptake, ion-exchange capacity, dimensional stability, and proton conductivity. Methanol permeability experiment was carried out to analyze the compatibility of prepared membranes toward direct methanol fuel cell application and found the lowest methanol permeability for PAS-5. Also, the membranes reveal excellent thermal, mechanical, and physicochemical properties for their application toward high-temperature electromembrane processes.
