The influence of the polyaniline initial oxidation states on the corrosion of steel with composite coatings
(Elsevier Science Sa, Lausanne, 2018)
The chemically synthesized polyaniline in the powdered form by the procedure recommended by IUPAC is reprotonated using sulfamic, citric, succinic and acetic acid. The UV-vis spectroscopy is applied to estimate doping ...
Tailoring the properties of waterborne polyurethanes by incorporating different content of poly(dimethylsiloxane)
(Progress in Organic Coatings, 2021)
A series of novel waterborne polyurethanes (WBPUs) was synthesized using alpha,omega-dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine ...
Transparent PMMA/silica nanocomposites containing silica nanoparticles coating under supercritical conditions
(Elsevier Science Sa, Lausanne, 2013)
This work reports the preparation of PMMA/silica nanocomposites with high optical transparency and enhanced mechanical properties using a melt compounding method. The surface of SiO2 particles was modified with a ...
The effect of ceria and zirconia nanoparticles on the corrosion behaviour of cataphoretic epoxy coatings on AA6060 alloy
(Elsevier Science Sa, Lausanne, 2019)
In this work an attempt was made to produce epoxy coating doped with ceria (CeO2) and/or zirconia (ZrO2) nanoparticles, in single step electrophoretric deposition process. Deposition was carried out on AA6060 cataforetically ...
The sorption characteristics and thermal stability of epoxy coatings electrodeposited on steel and steel electrochemically modified by Fe-P alloys
(Elsevier Science S.A., 1998)
The corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel and steel electrochemically modified by Fe-P alloys of different phase structures have been investigated during exposure to 3% NaCl. ...
Polyurethane networks based on polycaprolactone and hyperbranched polyester: Structural, thermal and mechanical investigation
(Elsevier Science Sa, Lausanne, 2019)
A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was ...
Hybrid acrylic nanocomposites with excellent transparency and hardness/toughness balance
(Elsevier B.V., 2020)
The composite nanofibers were used as reinforcement in acrylic polymer for the overall enhancement of thermo-mechanical properties, adhesion between fibers and matrix, and fracture toughness of the final nanocomposite since ...
The effect of resin concentration and electrodeposition bath temperature on the corrosion behaviour of polymer-coated steel
(Progress in Organic Coatings, 1990)
A.C. impedance measurements carried out on epoxy-resin electrocoated steels have been used to determine the pore resistance, capacitance and relative permittivity of the organic films. The time dependence of these ...
Influence of substrate on the formation and growth kinetics of cathodic electrocoat paint
(Elsevier Science Sa, Lausanne, 1995)
Cataphoretic deposition of an epoxy primer was carried out on four different substrates: bare steel; phosphated steel; bare zinc-plated steel; and phosphated zinc-plated steel. Film growth was followed by observing the ...
The influence of zinc surface pretreatment on the adhesion of epoxy coating electrodeposited on hot-dip galvanized steel
(Elsevier Science Sa, Lausanne, 2007)
The adhesion and electrochemical properties of epoxy coatings electrodeposited on hot-dip galvanized steel with and without passive films were investigated during exposure to 3% NaCl. The passive films were formed in hot ...
