Soy polyester urethane/TiO₂and Ce-TiO₂nanocomposites: preparation, characterization and evaluation of electrochemical corrosion resistance performance

Abstract

Eco-friendly soy polyester urethane nanocomposite coating materials were prepared by dispersing TiO2 and Ce-TiO2 nanoparticles in a 3-isocyanatopropyltriethoxysilane (IPTES) modified soy oil (SO) polyester urethane (PEUTES) matrix.

Hyperbranched Soya Alkyd Nanocomposite: A Sustainable Feedstock-Based Anticorrosive Nanocomposite Coatings

“…However, literature reveals that coatings based on alkyds failed to provide satisfactory performance in stringent and extreme corrosive environments. , To surpass this obstacle and enhance the anticorrosive properties of alkyd coatings, different types of modifications have been reported. For example, nanocomposite synthesis by dispersing nanofillers such as ZrO 2 , TiO 2 , ZnO, and Fe 2 O 3 nanoparticles, and conducting polymers, etc . It has been observed that the nanocomposites exhibit good mechanical, thermal, ultraviolet (UV) protection and anticorrosive properties and thus offer a promising, smart, and economical way to develop new generation anticorrosive materials .…”

Reduced Graphene Oxide Reinforced Waterborne Soy Alkyd Nanocomposites: Formulation, Characterization, and Corrosion Inhibition Analysis

“…This suggests that the coatings possess strong adhesion and good plasticity that induces higher stress bearing ability to the coatings (Figure S4). 41 In addition all the nanocomposite coatings with different ratios of RGO are found to pass the impact resistance and 1/8 in. conical mandrel bend test due to the presence of flexible moieties like ether linkages and long aliphatic chains of soy oil.…”

“…The best fitted equivalent circuit for coatings with single time constants in the given corrosive media (Figure S5) consist of R s (solution resistance), R pore (pore resistance), and Q (constant phase elements). The deviation in their values indicate a change from ideal capacitance value which can be due to the dispersion effect . The extent of deviation can be expressed by n .…”

“…The deviation in their values indicate a change from ideal capacitance value which can be due to the dispersion effect. 41 The extent of deviation can be expressed by n. If the value of n = 1, then Q gets converted into C, which indicates the formation of double layer capacitance between solution and the electrode, when n approaches 0, it starts to act as a resistor. 52 However, it is worth mentioning that as n approaches closer to 1 (i.e., 0 < n < 1), it begins to show capacitive behavior.…”

Cross‐linked waterborne alkyd hybrid resin coatings modified by fluorinated acrylate‐siloxane with high waterproof and anticorrosive performance

“…Therefore, in comparison, the diameter of the cross‐linked FASAR6 coating with other coatings in the Nyquist plot (Figure A), the cross‐linked FASAR6 coating provided better corrosion protection ability. On the other hand, the impedance modulus at the lowest frequency ( |Z| 0.01 Hz ) in Bode plot can use as a semi‐quantitative indicator of coating's barrier performance . The Bode‐modulus plots of FASAR6 showed a high| Z| 0.01 Hz value (4.74 × 10 4 Ω cm 2 ) at the onset of immersion (Figure B), which were two orders of magnitude higher than that of FASAR0.…”
