Electroactive Polymer-Based Nanostructures and Nanocomposites for Sensing Applications

Electroactive polymers (EAPs) are an intriguing group of materials suitable for next-generation sensing applications. Sensor technologies have revolutionized and simplified the living and working environment of human beings through their applications in almost all fields by detecting/collecting signals in various forms. Sensors improve our ability to comprehend and report on the environment around us. Herein we have reviewed the major types of EAP based sensors made by using polypyrrole (PPy), polyaniline (PANI), and poly (3,4-ethylene dioxythiophene) (PEDOT). Conducting polymers can be utilized for various gas, humidity, temperature, and pressure sensors due to their key characteristics including low weight, high stain capability, good flexibility, low voltage applicability, room temperature operability, rapid response, and high energy efficiency. In recent decades, polymer electrolyte-based nanostructures and nanocomposites have received significant attention for sensing applications. Due to their superior mechanical and detecting response qualities, polymer electrolyte membranes can possess highly responsive sensors for practical applications.
