Recent advances in the applications of substituted polyanilines and their blends and composites

Abstract

Conducting polymers remain as a key invention to the researchers in the last 3 decades. Among them, polyaniline serves as a potential candidate with feasible strategies to solve the current problems. Polyaniline is known for its extraordinary features such as ease of synthesis, low cost, considerable electrical conductivity, rich chemistry and strengthened biocompatibility. The scientific world has now diverged to the area of substituted polyanilines in the recent past owing to the efficient solubility, processability and extended applications in different fields. This review highlights the application aspects of the derivatives of polyanilines and their blends and composites in recent years. The wide application potentials of substituted polyanilines and their blends and composites in diverse fields such as in sensors, electrochromic display devices, solar cells, supercapacitors, batteries, semiconductors and anticorrosion materials, and in a variety of biological applications, have been highlighted. This review would bring new insights into polymer researchers to unravel novel applications.
