Polyindole Based Nanocomposites and Their Applications: A Review

Abstract

Polyindole (PIn) is hetroatomic organic molecule which belongs to the fused-ring family have emerged in the past several decades as promising materials due to their unique physical and electrochemical properties. PIn was successfully synthesized by chemical polymerization of indole. Properties of PIn can be improved by mixing polymer with conducting metals, metal oxide, carbon nanocomposites and other materials. Polyindole nanocomposites (PNCs) were characterized through various spectral, thermal and electrical methods. FT-IR (Fourier transform infrared spectroscopy) spectra confirmed the formation of PNCs and SEM (Scanning electron microscopy) reveal the microstructure of surface of PNCs. Thermal characterization revealed that thermal stability of PNCs increases with addition of metal, metal oxide, carbon nanocomposites and other materials. These studies revealed that PNCs of PIn with other metals have an important influence on supercapacitors electrochemical devices, catalysis, anticorrosion, diodes, sensor and biology related applications. This review provide an overview of the preparation of PIn and their composites, followed by their application in various fields with future perspectives.

Development of polyindole/tungsten carbide nanocomposite-modified electrodes for electrochemical quantification of chlorpyrifos

“…Recently, conducting polymer-based nanostructures containing carbonaceous and inorganic nanomaterials have been used in electrochemical studies for various applications [40][41][42][43][44]. Amongst the family of conducting polymers, polyindole (PIN) has an edge over other, due to its sustained polymerization, high electrical conductivity, low manufacturing cost and less toxicity [45][46][47][48][49]. Sensing behavior of PIN is modified through doping transition metal-based dopants that chanalize the electron transfer mechanism through polaron formation [50].…”

Microwave-Induced Polyindole on Cobalt MOF-Electrodes for High-Performance Supercapacitors

“…Among conducting polymers, Polyindole (PIn) possesses a fused aromatic molecular structure of polypyrrole and paly (para-phenylene), getting significant research interest in various applications owing to its high redox activity, switchable electrochromic performance, and better thermal stability. [24][25][26][27] The report shows that it offers better cycle stability and slow hydrolytic degradation compared to PANI and PPy while used as electrodes for energy storage applications. Also, it never forms any salts during its charging or discharging phase supports to reduce its internal resistance and enhance conductivity.…”
