“…6,[8][9][10]13) Recently, researchers have investigated magnetic nanocomposite materials for scientific and technological applications. [15][16][17][25][26][27] In particular, some coated polymers, such as poly(m-phenylenediamine), poly(1naphthylamine) and polyaniline, [28][29][30] have been studied to protect the chemical and physical properties of magnetic nanoparticles in technological applications. More specifically, researchers are very interested in polyvinyl pyrrolidone (PVP), polyvinyl alcohol (PVA) or organic materials for biomedical applications.…”

Zn x Fe1−x Fe2O4 nanoparticles (x = 0.0–0.25) were synthesized by the coprecipitation method. Their microstructure was investigated by X-ray diffraction with Rietveld refinement software, energy-dispersive X-ray spectroscopy, transmission electron microscopy, and Fourier transform infrared absorption spectroscopy. Their thermal, magnetic properties were investigated by thermogravimetric analysis and vibrating-sample magnetometer. The nanoparticles exhibited superparamagnetic properties, with a maximum saturation magnetization of 80.2 emu g−1 in H = 11 000 Oe at room temperature for sample with x = 0.20. The Zn nonmagnetic element content is related to the cation distribution in the superlattices and magnetic moment of the particles. The Zn0.15Fe0.85Fe2O4 nanoparticles were coated with polyvinyl pyrrolidone (PVP) with different PVP mass. Their core–shell structure was investigated, the results showed that their chemical stability and saturation magnetization were greater than those of pure Fe3O4. PVP has biological compatibility; thus, Fe0.85Zn0.15Fe2O4/PVP0.75 nanocomposite has the potential to be widely used in medical biology, science and technology.

“…A related study demonstrated that the magnetite acrylamide amino-amidoxime nanocomposites prepared using the in situ method exhibited excellent sorption properties and could, therefore, be utilized for treating U(VI) present in aqueous solution [109]. In another work, magnetite/poly (1-naphthylamine) nanocomposite was prepared using the in situ method and then used for As (III) removal [110]. Another nanocomposite composed of poly(N-vinylcarbazole) and graphene oxide was fabricated in a study and then used for adsorbing heavy metals from aqueous solutions.…”

Polymeric nanocomposites (PNC) have an outstanding potential for various applications as the integrated structure of the PNCs exhibits properties that none of its component materials individually possess. Moreover, it is possible to fabricate PNCs into desired shapes and sizes, which would enable controlling their properties, such as their surface area, magnetic behavior, optical properties, and catalytic activity. The low cost and light weight of PNCs have further contributed to their potential in various environmental and industrial applications. Stimuli-responsive nanocomposites are a subgroup of PNCs having a minimum of one promising chemical and physical property that may be controlled by or follow a stimulus response. Such outstanding properties and behaviors have extended the scope of application of these nanocomposites. The present review discusses the various methods of preparation available for PNCs, including in situ synthesis, solution mixing, melt blending, and electrospinning. In addition, various environmental and industrial applications of PNCs, including those in the fields of water treatment, electromagnetic shielding in aerospace applications, sensor devices, and food packaging, are outlined.

“…Among them, PANI stands out as the most viable due to its high conductivity, high stability in the doped state, and low-cost production. ,, Consequently, PANI has been studied for many applications such as corrosion, , printed circuit boards, antistatic coatings, electrochromic displays, charge storage devices, , hole transport layers (HTLs) in perovskite solar cells, − light-emitting diodes (LED), waste removal, , and biosensors . However, PANI’s limited solubility in common organic solvents and its electrochemical instability have prompted our group and others to explore PANI derivatives as alternatives to address PANI’s limitations. − For example, poly(1-naphthylamine) has been studied by Ahmad and co-workers, and later by Riaz’s group, in a number of applications such as anticorrosion and antibacterial coatings, − photolytic degradation of dyes, , and wastewater remediation .

Side chain alkyl groups have become the standard for incorporating solubilizing groups into conjugated polymers. However, the variety of alkyl groups available and their location on the polymer's backbone can contribute to the packing of the polymer chains in many different ways, resulting in many different morphologies in the polymer that can affect its properties and performances. In this paper, we investigate the effects on the conductivity of nine phenothiazine-containing polyaniline derivatives (P1−P9) with alkyl or aryl side chains on the phenothiazine core while also varying the number of methyl groups on the pphenylenediamine unit. 1 H nuclear magnetic resonance spectroscopy, ultraviolet−visible spectroscopy, differential scanning calorimetry, scanning electron microscopy, atomic force microscopy, and wide-angle X-ray scattering (WAXS) were all used to study the polymers' structures, physical and thermal properties, and morphologies. The t-butylphenyl substituent on the phenothiazine core seems to provide more rigidity in the polymer's backbone resulting in higher T g for series 3, while series 2 containing the 2hexyldecyl-substituted polymers had the lowest T g , which is attributed to the large volume of the side chain, that limits interchain interactions. Consequently, series 2 had the lowest conductivity. However, the strongest effect on the conductivity was seen from the tetramethyl groups on the PPDA unit, which resulted in the lowest conductivity in each series due to torsional strain (twisting) in the polymer's backbone. The WAXS data suggest mostly amorphous films; thus, the conductivity in these materials seems to be dominated by a multiscale charge transport phenomenon that occurs in amorphous conjugated materials. Our results will aid in the understanding of side chain engineering of PANI derivatives for their optimum performances.
