“…46 In general, PPy, as a conjugated conductive polymer, has been explored for many applications, for instance, light-emitting diodes, [47][48][49][50] supercapacitor, 51,52 medical treatment, 53 catalysts, 54 and corrosion protection. 55,56 Moreover, based on its strong near-infrared light absorption (wavelength >700 nm), good in vivo biocompatibility, low biotoxicity, and facile chemical polymerization, PPy exhibits a great potentiality in the field of photothermal evaporation, and it is also studied extensively as the photothermal agent for cancer removal. 42,53,57 In the reported work of He et al, they fabricated a solar-to-steam generation device (PPy-coated M-PDVB-PS) via PDVB-PS porous polymers monolithic foam and PPy, displaying a high water evaporation efficiency was at approximately 87% under 1 sun, but PDVB-PS porous polymers monolithic foam needed a long reaction time to be synthesized.…”

“…In recent years, benefiting from the exploration of a number of photothermal, including carbon-based materials (carbon black, CNTs, graphene, GO, and rGO), 18 [40][41][42][43][44][45] because of their broadband and high light absorption, great progress has been made in the design and fabrication of high efficiency solar steam generation devices. 55,56 Moreover, based on its strong near-infrared light absorption (wavelength >700 nm), good in vivo biocompatibility, low biotoxicity, and facile chemical polymerization, PPy exhibits a great potentiality in the field of photothermal evaporation, and it is also studied extensively as the photothermal agent for cancer removal. 55,56 Moreover, based on its strong near-infrared light absorption (wavelength >700 nm), good in vivo biocompatibility, low biotoxicity, and facile chemical polymerization, PPy exhibits a great potentiality in the field of photothermal evaporation, and it is also studied extensively as the photothermal agent for cancer removal.…”

It is well recognized that combining nonpotable water with solar energy to desalinate water and produce water vapor is an effective route to solve the shortage of fresh water. However, the solar vapor generation suffers from either low solar energy efficiency or complex and high-cost devices. Herein, we explore a black membrane based on polypyrrole (PPy) and filter paper to enhance solar-to-vapor conversion performance, thus providing a low-cost, stable, and strong efficient solar vapor generator. This device displays high solarto-vapor conversion efficiencies of up to approximately 92.2% and 95.6% under irradiation of 1 and 4 kW m −2 , respectively. Therefore, this paper-based high solar-to-vapor conversion and scalable evaporator provides a promising solution to the problem of freshwater scarcity and nonrenewable recourses.

“…It seems interesting to use PhA anions as a corrosion inhibitor introduced into solution during the electrochemical synthesis of thin polypyrrole films. Since the electropolymerization of the monomer begins on passive Cu, an aqueous solution with passivating properties is used to prevent the metal from corrosion [53]. It has long been known [54] that PhA and its salts can be used as primers on a metal before an organic coating is applied, which apparently improves its adhesion.…”

This article continues the review of studies (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) dealing with the passivation of various metals by solutions of organic corrosion inhibitors. It provides an overview of papers on the passivating properties of organophosphates, their complexes and salts. The results of corrosion and electrochemical studies, as well as studies on the composition and structural features of surface layers on metals by a variety of physicochemical methods are considered. Organic phosphorus compounds are often called organophosphates, especially in the case of pesticides and even toxic agents. Of course, it is unlikely that such materials have application prospects for the inhibition of metal corrosion. That is why in this series of reviews we consider organophosphates in a narrower sense limited to phosphoric acid esters and their salts, as well as phosphonic acids, their salts or complex compounds with metal cations [1][2][3][4]. The easy synthesis of acid esters of phosphoric acid, the stability of mono-and disubstituted ester anions, their ability to form complexes and hydrophobic passive films on oxidized metal surfaces has been known for a long time [1]. They can be used for the passivation of phosphated metal surfaces, and their salts with amines are used within deicing formulations. These salts can inhibit not only corrosion but also formation of deposits, so they are used in two-phase systems in the oil industry. Since higher homologues are more effective, the solubility of alkylphosphonic acids is commonly increased by ethoxylation. Salts of these acids are used in cooling lubricants, e.g., waterbased cutting fluids. The low toxicity, ability to be chemisorbed on a metal surface, and some useful technological properties of acid esters of phosphoric acid continue to motivate researchers to look for effective corrosion inhibitors of various metals among these compounds and to study their protection mechanisms [5][6][7][8][9][10][11][12][13][14]. Key words: metal corrosion, inhibitors, metal passivation, organophosphates.

“…Thus, there is a crucial need for new corrosion control strategies, which show high performance and are economic and pollution free. Commonly used effective corrosion control strategies include cathodic protection, addition of corrosion inhibitors, and use of protective coatings . Among these, corrosion protective coating/anticorrosion coating is the most preferred method, which provides an effective physical barrier between the surface of the metal to be protected and corrosive environment…”

In the present work, PPy, ZnO, and polypyrrole/zinc oxide (PPy/ZnO) microcomposites (1, 2, and 5 wt%) were prepared and their properties have been tuned for anticorrosion applications on low carbon mild steel. The synthesized products: ZnO, PPy, and composites were characterized by various sophisticated analytical techniques such as XRD, FTIR, Raman, FESEM, EDX, UV–VIS, TGA, and BET. The band frequencies observed at 480 and 588 cm−1 in FTIR spectrum correspond to stretching vibrations of Zn‐O and N‐H bonds, respectively, broadening of the bands in the composites indicate strong interactions between ZnO and PPy matrix. The potentiodynamic polarization study of PPy and PPy/ZnO composite was carried out in 3.5% NaCl solution to investigate the corrosion resistance efficiency. PPy/1 wt% ZnO (Icorr = 190 nA) composite coating on low carbon mild steel was observed to exhibit best corrosion protection property compared to PPy (121 μA), 2 and 5 wt% ZnO (242, 295 nA) composites. © 2019 Wiley Periodicals, Inc.
