Interfacial growth of free-standing PANI films: toward high-performance all-polymer supercapacitors

Abstract

A covalently cross-linked polyaniline network is synthesized via interfacial Buchwald-Hartwig polymerization/deprotection, enabling the generation of additive/binder-free and high-performance conducting thin-films for energy storage.

PANI-Based Wearable Electrochemical Sensor for pH Sweat Monitoring

“…Moreover, PANI showed excellent pH sensitivity when utilized in different types of PANI-based pH sensors [40]. PANI films can be obtained by different fabrication methods such as in situ chemical oxidative polymerization [41], γ-irradiation [42], spraying and drop casting [43], plasma polymerization [44], Buchwald-Hartwig polymerization [45], dip coating [46], spin coating [47] and electro-polymerization [48]. Among the different manufacturing methods, the electrochemical one appears extremely interesting because it is fast, easy to scale and simple.…”

Improved electrochemical properties of polypyrrole with cucurbit[6]uril via supramolecular interactions

“…To improve the functionalization of conducting polymers, different microstructures with varied morphologies were realized to demonstrate high conductivity, biocompatibility, and good thermal and environmental stability. [29][30][31] With an alternative strategy, the morphology control of polymers can be achieved through hybridization with metal or carbonaceous nanoparticles [32][33][34] for novel fundamental and intriguing applications. 35,36 With good conductivity, polypyrrole was generally employed as a supporting additive of metal oxide nanoparticles, carbon materials, and crystal materials to improve their electrochemical capabilities.…”

Preparation of ZnCo2O4@PANI core/shell nanobelts for high-performance asymmetric supercapacitors

“…22 Conducting polymers (CP), such as polyethyl-enedioxythiophene (PEDOT), polypyrrole (PPy), polythiophene (PTh), and polyaniline (PANI), have been intensively explored as pseudocapacitive materials due to their high electrical conductivity and fast reversible faradaic reactions. [23][24][25][26] However, the main difficulty in using CP-based electrodes in supercapacitors is their weak cycling stability during the charge/discharge process. 27,28 In particular, PANI is one of the most widely used CP materials that has some advantages, such as high electrical conductivity (3.58 × 10 −11 S nm −1 ), 29 good environmental stability, low-cost and ease of synthesis.…”
