Polyamidoamine as a clay modifier and curing agent in preparation of epoxy nanocomposites
(Elsevier Science Sa, Lausanne, 2019)
In the present study the commercial multifunctional fatty acid polyamidoamine (PAA) was for the first time simultaneously applied as a curing agent and clay modifier for epoxy/clay nanocomposites (NC) based on diglycidyl ...
Graphene-based antibacterial composite coatings electrodeposited on titanium for biomedical applications
(Elsevier Science Sa, Lausanne, 2015)
The graphene based silver/hydroxyapatite/graphene (Ag/HAP/Gr) composite coatings were produced by electrophoretic deposition (EPD) on titanium to assemble porous bioactive homogenous coatings, with improved corrosion ...
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 ...
The protective properties of epoxy coating electrodeposited on Zn-Mn alloy substrate
(Elsevier Science Sa, Lausanne, 2015)
The epoxy coating was cataphoretically deposited on steel and steel modified by electroplated Zn-Mn alloy of different chemical contents. The samples were immersed in 0.5 mol dm(-3) NaCl solution for 60 days. The electrochemical ...
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) ...
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 ...
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 ...
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 ...
