“…Further, the lm thickness values of root (962.5060Å) and stem (1694.9741Å) were increased due to the chemisorption of inhibitor molecules on mild steel. [33][34][35][36] The obtained lm thickness values are presented in Table 1. The results of Ellipsometer studies revealed that there is excellent chemisorption of C. roseus on the mild steel surface.…”

Application of anticorrosive coating on metal surface enhances the durability of the metal. Anticorrosion can be achieved by the incorporation of conducting nanomaterials like polyaniline or its nanohybrid to a coating material. Thus, bio‐based epoxy nanocomposites were fabricated by the in situ method using polyaniline nanofiber‐carbon dot nanohybrid (0.50 and 1 wt % with respect to epoxy), as the anticorrosive material. The epoxy resin was obtained by polycondensation of bisphenol‐A, sorbitol, and monoglyceride of castor oil (mole ratio of 16:3:1), as hydroxyl compounds with epichlorohydrin (1:3 equivalent, hydroxyl:epichlorohydrin). The morphological analyses of the nanocomposites revealed the uniform dispersion and good compatibility of the nanohybrid in the epoxy matrix. The thermosets demonstrated good tensile strength (30 MPa), elongation at break (45%), scratch resistance (>10 kg) and impact resistance (14.75 kJ/m), good thermal stability (above 250°C), and chemical resistance. The anticorrosion study of the nanocomposites showed excellent corrosion protection efficiency (corrosion rate: 5.68 × 10−3 mils per year) in 3.5 wt % NaCl compared to the pristine epoxy system. Therefore, this bio‐based thermosetting epoxy nanocomposite was demonstrated as efficient anticorrosive material. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47744.

“…Corrosion inhibition mechanism of BPTA and BPTA synergistic with 0.001 g, of TiO 2 -NP in corrosive environment was demonstrated by the adsorption of BPTA and BPTA synergistic with 0.001 g, of TiO 2 -NP molecules onto the MS surface. The inhibition efficiencies of the BPTA and BPTA synergistic with 0.001 g, of TiO 2 -NP are related to considerable factors such as alloy type, acidic environment, structure of inhibitor including adsorption centers sites, electronic structure, and inhibitor chemical characteristics, interactions type between inhibitor molecules and MS surface [52]. The obtained results (experiments and theoretical), adsorption, different inhibitor molecules may be adsorbed at different sites on the surface of MS.…”

A new benzylidene derivative, namely 3,, has been synthesized and instrumentally confirmed with Elemental Analysis (CHN), Nuclear Magnetic Resonance (NMR), and Fourier Transform Infrared Spectroscopy (FT-IR). Titanium Dioxide (TiO 2 ) nanoparticles (NPs) were synthesized and characterized by X-ray. The mutualistic complementary dependence of BPTA with TiO 2 nanoparticles as anticorrosive inhibitor on mild steel (MS) in 1.0 M hydrochloric acid has been tested at various concentrations and various temperatures. The methodological work was achieved by gravimetric measurement methods complemented with surface analysis. The synthesized inhibitor concentrations were 0.1 mM to 0.5 mM and the temperatures ranging from 303-333 K. The BPTA with TiO 2 -NP as a synergistic inhibitor becomes superior inhibitive effects with more than 96% inhibition competence of MS coupons in a harsh acidic medium. The efficiency of the inhibition improved with increasing BPTA content and also increase with the Synergistic effects of BPTA with TiO 2 -NP. The excellent effectiveness was performed with the 0.5 mM concentration of BPTA and become higher with adding of TiO 2 -NP rising to the maximum inhibition efficiency (IE). However, the inhibition efficacy declined as the temperature rises. Results of BPTA as corrosion inhibitor indicated the obedience of the adsorption of the inhibitor of mixed type on the surface of MS to Langmuir adsorption isotherm. It was found that the BPTA and performance depend on the Synergistic effects, concentrations of the TiO 2 -NP and BPTA, in addition to the solution temperature. Nevertheless, the quantum calculations have confirmed the direct correlation of the electronic characteristics of BPTA with the corrosive inhibitive influence.
