Summary: This study presents the design of a polymer-film-based gas detection sensor using different types of polyaniline as active layers. The resistive sensors with PANI layers have the advantages of easy preparation and low production cost. The polymer films exhibit high sensitivity to gas concentrations at room temperature. The developed sensor works based on the principle of electrical resistance shifting with gas concentration. Three different polymerization solutions are used to synthesize the PANI active layers, and the PANI layers polymerized in acetic acid solutions show good sensitivity towards ammonia.

Summary: This study constructed a flexible sensor based on mesh PANI/Ti3C2Tx composite nanofibers, which exhibited excellent performance in NH3 sensing response and flexible bending stability. The improved sensing properties can be attributed to the formation of Schottky junctions between PANI and Ti3C2Tx nanosheets, improved protonation degree of PANI, and the special three-dimensional mesh fiber structure.

Summary: This study successfully designed and prepared a novel hybrid antibacterial polymer based on polyaniline and halamine, and characterized and tested it. The results showed that the hybrid material exhibited strong antibacterial activity, inhibiting the growth of bacteria effectively. Additionally, the added surfactant influenced the release of active chlorine from the hybrid, diminishing the antibacterial efficacy.

Summary: The search for higher-quality nanomaterials for medicinal applications is ongoing. Electrospun fibers, which have similarities with natural tissues, have made significant progress in medical applications. Combining nanoparticles and nanofibers in composite materials allows for additional functions, such as photothermal, magnetic response, biosensing, antibacterial, drug delivery, and biosensing. There are two primary ways to prepare nanofiber and nanoparticle hybrids (NNHs): through single-step electrospinning or through the self-assembly technique. This paper focuses on the application of NNHs in drug release, antibacterial effects, and tissue engineering, utilizing biocompatible polymer composites.

Summary: A high surface area of manganese sulfide (MnS) nanoparticles was demonstrated via a simple solution method. The in-situ polymerization of aniline without HCl was achieved with the help of acidic groups on the graphene oxide surface. The addition of graphene oxide (GO) and polyaniline (PANI) improved the specific capacitance and interfacial interactions in the MnS/GO/PANI nanocomposite, making it a promising choice for high-performance supercapacitor applications.

Summary: Nanofiber membranes prepared by electrospinning technology have been considered as excellent candidates for air filtration, due to their high porosity, small pore size, and good connectivity. This review summarizes the recent research progress on electrospun nanofibers as air filters, including fabrication methods, filtration performances, advantages, and disadvantages. The prospects for using complex-structured nanofibers in air filtration are also discussed.

Summary: In this study, microsphere-like Co-doped SnS grown on carbon nanofibers (Co-SnS@CNF) was prepared by electrospinning, hydrothermal method, and annealing treatment. Co-SnS@CNF exhibits excellent electrochemical performance due to the special microsphere structure with more electrochemical active sites and lower resistance of ion and charge transfer by Co doping. The assembled Co-SnS@CNF as a symmetrical supercapacitor device achieves an energy density of 20.89 Wh Kg-1 and a power density of 376 W Kg-1 at a current density of 1 A g-1, while demonstrating ultra-high cycle stability. Therefore, Co-SnS@CNF shows great potential for application in flexible self-supporting supercapacitors.

Summary: Adding PANI nanofibers into LDPE can improve space charge distribution, with doped PANI nanofibers having higher conductivity and more effectively suppressing space charge accumulation, but also reducing the DC breakdown strength of the nanocomposites. Overall, dedoped PANI nanofibers are superior for the DC dielectric properties of LDPE.

Summary: A hydrogen sulfide gas-sensitive chemiresistive sensor was fabricated using screen printing on a flexible PET substrate with a nanocomposite of PANI/WO3/CuCl2. The sensor showed good gas-sensing capabilities, and PANI/WO3/CuCl2 was found to improve the reversibility and humidity sensitivity of the sensor.

Summary: Intrinsically conducting polymers undergo changes in molecular structure and material properties in highly oxidizing conditions or positive electrode potentials. These changes depend on experimental conditions and chemical environment. While these changes may be beneficial for some applications, they often negatively affect the material's performance.
