Polyurethane-TiO2 nanocomposite coatings from sunflower- oil-based amide diol as soft segment

Vegetable oil based environmentally friendly polyurethane-TiO2 nanocomposite coatings have
been synthesized by using sunflower oil derived diol, toluene diisocyanate and TiO2 nanoparticles.
The chemical structure was confirmed by FTIR and NMR techniques while physico-chemical testing
was carried out by standard laboratory methods. Physico-mechanical and anticorrosive tests of the
coatings (in different corrosive media) have been investigated by standard methods. In addition to
this the morphology and thermal stability behavior of the coatings have been carefully investigated
by different techniques like XRD, TEM, TGA/DTG and DSC. The comparison of the performance
of nanocomposites with the respective virgin polyurethane coatings reveals that the
dispersion of nanoTiO2 enhanced the mechanical, corrosion and thermal stability behavior of the
polymer. The synthesized nanocomposites can be used safely upto 250–275 C. These sunflower
oil derived polyurethane nanocomposites can be used in the world of protective coatings, as an
alternative of petroleum derived corrosion protective coating materials.
