Pani-Based Nanocomposites for Electrical Applications: A Review
Keywords:PANI nanocomposites, electrical, doping, n-doped carbon material
Including supercapacitors, rechargeable batteries, and fuel cells, conducting polyaniline (PANI) has been widely used in electrochemical energy storage and conversion technologies due to its high conductivity, ease of synthesis, high flexibility, low cost, and distinctive redox properties. Because of its poor stability as a super-capacitive electrode, pure PANI cannot keep up with the rising demands for more N-active sites, better power/energy densities, and more stable molecular structures. These drawbacks as a super-capacitive electrode can be overcome by combining PANI with other active materials such as carbon compounds, metal compounds, and other conducting polymers (CPs). Recent PANI research focuses mainly on PANI-modified composite electrodes and supported composite electrocatalysts for fuel cells and rechargeable batteries, respectively. Due to the synergistic effect, PANI-based composites with various unique structures have shown superior electrochemical performance in supercapacitors, rechargeable batteries, and fuel cells. PANI typically functions as a conductive layer and network in different PANI-based composite structures. This review also discusses N-doped carbon materials produced from PANI because they are frequently employed as metal-free electrocatalysts for fuel cells. We conclude by providing a quick summary of upcoming developments and future research directions in PANI
