Corrosion of mild steel with composite polyaniline coatings using different formulations
(Elsevier Science Sa, Lausanne, 2015)
The protective abilities of composite coatings based on electrochemically and chemically formed polyaniline powder against the corrosion of mild steel were investigated. A polyaniline powder has been prepared in the form ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Protective properties of cataphoretic epoxy coating on aluminium alloy AA6060 modified with electrodeposited Ce-based coatings: Effect of post-treatment
(Elsevier Science Sa, Lausanne, 2015)
Ce-based conversion coatings (CeCCs) are a promising alternative to toxic chromate coatings on the metal substrates. In this work the CeCCs were electrodeposited on aluminium alloy AA6060 from aqueous solution of Ce(NO3)(3) ...
The influence of thin benzoate-doped polyaniline coatings on corrosion protection of mild steel in different environments
(Elsevier Science Sa, Lausanne, 2013)
The corrosion process of mild steel in the presence of benzoate-doped polyaniline coatings exposed to different environments (3% NaCl, atmosphere, and the Sahara sand) has been investigated. This system was also tested for ...
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 ...
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 ...
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 ...
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 ...
