Recent progress in the preparation of polyaniline nanostructures and their applications in anticorrosive coatings

Thermoresponsive polyaniline nanoparticles: Preparation, characterization, and their potential application in waterborne anticorrosion coatings

“…These particular characteristics enable PANIs to be used in many potential applications, such as tissue engineering [3,4], anticorrosion coatings [5,6], supercapacitors [7,8], solar cells [9], and sensors [10].…”

“…PANI is considered to be one of the best pigments for the anticorrosion coatings because of its unique redox tunability, environmental stability, simple acid-base doping-dedoping process, and passivation of the oxide layer between the metal and the coating [6]. In the water-based anticorrosion coating systems, the waterborne PANI-NPs attract much interest not only because of the increasing requirements for environmental protection, but also because of their nanoscale dispersion in the matrix of waterborne coating polymers, which is a beneficial factor for the promotion of anticorrosion performance [29].…”

“…Since the processing of PANIs using these organic solvents leads to serious environmental pollution and potential damage to human health, ecofriendly processing of waterborne PANIs has attracted great interest in both academic and industrial research [5]. Waterborne PANI nanoparticles (PANI-NPs) are the simplest among many nanostructures of PANIs [6], which can be prepared from various approaches including self-doping [11,12], counterion induced method [13,14], and dispersing polymerization with specific stabilizers, such as poly(vinyl alcohol) (PVA) [15,16], polyacrylamide [17], poly(vinyl pyrrolidone) [18,19], hydroxypropylcellulose [20], chitosan [21,22], poly(N-isopropylacrylamide) [22], or sophisticated tailor-made copolymers [23][24][25][26][27]. Although so many kinds of PANI-NPs have been reported, research on smart waterborne PANINPs is still scarce [22,27,28].…”

A Polianilina No Cenário Ambiental: Uma Aborgagem Sobre Fotocatálise Heterogênea

“…Os principais estudos e aplicações da polianilina se relacionam com sensores/biosensores, transistores, eletrodos em baterias, supercapacitores, coberturas anticorrosivas, dispositivos fotovoltaicos e eletrocrômicos, fotocatalisadores, entre outras. 7,17,23,24 O uso da polianilina em aplicações ambientais envolve células solares sensibilizadas, 17,25,26 produção de hidrogênio, 27,28 e fotocatálise heterogênea para remoção de contaminantes e desinfecção. 21,[29][30][31] Na última década houve crescente aumento das publicações abordando processos fotocatalíticos e polianilina, além de outros polímeros condutores (Figura 1).…”

Electroactive polyurea/CNT composite-based electrode for detection of vitamin C

“…Since their discovery in the 1950s, conducting polymers have been extensively studied and showed great promise in a variety of applications [1][2][3][4][5][6][7]. Among various conducting polymers, polyaniline (PANI) has attracted much attention due to its ease of synthesis, unique and controllable chemical, electrical properties and long-term stability in air.…”
