Summary: In this article, a polydopamine/polyaniline decorated CNT composite (PDA/PANI@CNT) was synthesized for hybrid supercapacitor application. The structural and morphological features of the composite were characterized using various physicochemical techniques. The supercapacitive performance of the PDA/PANI@CNT electrode was evaluated and showed high specific capacitance and capacitance retention, indicating its potential as an electrode material for supercapacitors. Additionally, the biocidal potency of the composite was found to be better compared to PDA and PDA/PANI, suggesting the synergistic effect of CNT in enhancing the biological properties of PDA/PANI.

Summary: In this study, Cr2O3 nanocomposite with multi-walled carbon nanotubes (MWCNTs) was developed using an inexpensive and reproducible coprecipitation method to reduce volume changes and enhance electronic conductivity and mechanical strength. In-situ polymerization of aniline monomer was employed to coat the nanocomposite with polyaniline (PANI), improving lithium-ion conductivity and electron transportation, leading to excellent stability. The homogenous nanocomposite of Cr2O3-MWCNTs and PANI showed good electrochemical performance, with a discharge capacity of 815 mAh g-1 at 100 mA g-1 and a coulombic efficiency of 97.5%.

Summary: In this study, the removal of phenol from synthetic and real wastewater using a new polyacrylic acid-modified graphene oxide (GO-PAA) composite material was investigated. Results showed that the adsorption capacity of GO-PAA was double compared to un-modified GO, and under the optimum conditions (pH 2 and 25°C), GO-PAA was able to remove approximately 75% of phenol from synthetic wastewater. These findings suggest that adsorption using GO-PAA could be an effective and simple method for remediating pollution, especially in acidic conditions.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.

Summary: A coaxial optical fiber interferometer (COFI) with a polyacrylic acid (PAA)/polyaniline (PAni) film coating is proposed for ammonia sensing. The COFI is composed of two light-carrying single-mode fibers fused to a section of no-core fiber, forming an optical interferometer. The composite film formed by 5 wt% PAA mixed with 2 wt% PAni shows better performance, with a maximum sensitivity of 9.8 pm/ppm under the ammonia concentration of 50 ppm. The sensor exhibits good response time, recovery time, stability, and selectivity, making it suitable for monitoring ammonia leakage in various applications.

Summary: This study proposes a new method for producing polymer composites by adsorbing multiwalled carbon nanotubes on the surface of polystyrene spheres. The method allows control of cell size and conductivity of the composite. The study explores the effect of MWCNT concentration on the structure and electrophysical properties of the composites in a specific frequency range. The results show percolation behavior in the composite's conductivity and the formation of two subsystems of nanotubes on the PS surface, each influencing different frequency ranges.
