“…The signals at δ = 7.17 and 6.91 ppm are attributed to hydrogens on the benzene ring. Moreover, the signal at δ = 7.02 ppm corresponds to the hydrogen on the quinone ring . The NMR spectrum for DFAP shows overlapped peaks at δ = 6–8 ppm, which may be attributed to the complex signals resulting from the benzene and quinone rings.…”

Zinc-rich epoxy coating plays a major role in current heavy-duty corrosion protection solutions, yet high loading of zinc dust (ZD) weakens the coating flexibility and adhesion capability of the overall coating. This work demonstrated the successful incorporation of small amounts of rGO and aniline pentamer (AP)-based diamine into zinc-rich non-electroactive epoxy thermoset (NEET) as a novel heavy-duty anticorrosion coating composite. This coating composite promoted its wear resistance without sacrificing anticorrosion performance and adhesion ability while effectively reducing the loading of ZD. Based on a series of electrochemical measurements, an electroactive epoxy thermoset (EET) containing 5 wt % electroactive APbased diamine (DAAP) and 0.5 wt % rGO can replace 70 wt % ZD and shows equivalent anticorrosion performance under an accelerated salt-spray assay and electrochemical corrosion measurements. Furthermore, coatings containing DAAP and rGO exhibited improved wear resistance and good adhesion capability.

Nanoparticles have aroused widespread interest because of their unique surface structure and nano effect, which presents novel characteristics like as sound, light, electricity, magnetism, and thermal properties. However, two critical defects have hindered their applications: (1) poor processability resulting from the high melting temperature (e.g., >1000 °C) for some inorganic nanoparticles; (2) the restriction of the nano effect caused by the easy aggregation of the nanoparticles. To solve those issues, solvent-free nanofluids (SNFs) with hard cores and flexible organic chains were successfully designed and fabricated at the beginning of the twenty-first century. The promising technology of SNFs not only solved the dispersion problem of nanomaterials but also imparted novel functionalization to nanoparticles. Up to now, many researchers have been devoted to developing diverse cores and flexible organic polymer chains to endow SNFs with particular functions, such as conductivity, fluorescence, lubricity, and so on. However, there are few review reports on the research progress in the fabrication and applications of functional SNFs. To gain a better understanding of SNFs, this paper presents an overall investigation into the development, fabrication, as well as the applications of functional SNFs.

“…Polyaniline (PANI) and its derivatives such as polydiphenylamine (PDPA) are attractive conductive polymers useful for various applications such as rechargeable batteries, electrochromic display devices, sensors, corrosion‐protective coatings, etc. (Figure (a)) . To improve the processing capability or control the electronic properties of aniline, various substitution strategies have been investigated.…”
