Preparation and properties of short oil alkyd resin/TiO 2 nanocomposites based on surface modified TiO 2 nanoparticles

Alkyd resin/TiO 2 nanocomposites (NC) were prepared from short oil alkyd resin and TiO 2 nanoparticles (NPs) surface modified with in situ formed imine ligand, based on 3,4‐dihydroxybenzaldehyde and oleylamine, or with three gallic acid esters. The short oil alkyd resin was synthesized from sunflowe...

Description
Summary:Alkyd resin/TiO 2 nanocomposites (NC) were prepared from short oil alkyd resin and TiO 2 nanoparticles (NPs) surface modified with in situ formed imine ligand, based on 3,4‐dihydroxybenzaldehyde and oleylamine, or with three gallic acid esters. The short oil alkyd resin was synthesized from sunflower oil, phthalic anhydride, and trimethylolpropane. Unmodified and surface modified TiO 2 NPs were examined by transmission electron microscopy. Rheological investigation revealed that prepared dispersions have higher dynamic viscosity than pure alkyd resin. Using different characterization methods it was obtained that NCs have similar thermooxidative stability as alkyd resin, lower glass transition temperature, better barrier properties, enhanced hardness, better chemical resistance, and lower adhesion to the metal, except in the case of NC prepared using TiO 2 NPs surface modified with imine, which exhibited better adhesion to the metal than pure alkyd resin.
