Summary: Conducting polymers based hexagonal boron nitride (h-BN) nanocomposites, including polyaniline (PANI)/h-BN and polyaniline-polypyrrole (PANI-PPy)/h-BN, were successfully fabricated using a chemical oxidative polymerization approach. The synthesized materials exhibited desirable properties such as improved thermal stability and irregular morphological structures. The PANI/h-BN nanocomposites showed the highest capacitance and capacitance retention after multiple cycles compared to other materials. Furthermore, a hybrid asymmetric supercapacitor device composed of PANI/h-BN as the positive electrode and activated carbon (AC) as the negative electrode demonstrated superior performance in terms of specific capacitance, power density, and LED lighting time.

Summary: Recent years have seen a growing demand for flexible and portable high-power, high-density electronic devices. Researchers are particularly interested in flexible energy storage devices such as supercapacitors and batteries. Metal-organic frameworks (MOFs) are attractive for electrochemical applications because of their high porosity and ability to store high charges. Nanocomposite materials based on MIL-100(Fe) were synthesized using Polyaniline and Graphene (Gr) nanosheets. Multiple characterization approaches were utilized. PANI/Gr/MIL-100(Fe) was reported as a supercapacitor electrode with capacitive energy storage properties for the first time. It exhibited a maximum specific capacitance of 638 F/g at 1 A/g in acidic electrolyte, along with the lowest charge transfer resistance among the compounds produced. Furthermore, a PANI/Gr/MIL-100/Active carbon (AC) asymmetric supercapacitor showed exceptional electrochemical performance, achieving a high energy density (53 Wh/kg) and a high-power density (1225 W/kg). This outstanding performance is attributed to the facilitated electron transport structure, large surface area, and synergistic effects between the three components. It indicates a promising future for flexible next-generation supercapacitors.

Summary: Carbon nanofibers (CNFs) have attracted considerable attention due to their ability to enhance the properties of materials. This paper proposes a method to enhance the electrochemical performance and flexibility of CNFs by using electrostatic self-assembly and a dipping and drying strategy. The resulting PAN@rGO@PPy electrode shows specific capacitance of 203 F g(-1) and high energy density of 15 Wh kg(-1) in a flexible supercapacitor. It also demonstrates remarkable cycling stability after 10,000 cycles. The research provides valuable insights for the development of flexible energy storage devices.
