Surface modification of TiO2 nanoparticles with 1,1,1-Tris(hydroxymethyl)propane and its coating application effects on castor seed oil-PECH blend based urethane systems

Surface modification of peripheral hydroxyl groups of TiO2 with trimethylolpropane (TMP) was successfully carried out and characterized. This hybrid material (TiO2-TMP) was added in percentages to a polyol blend of castor seed oil (a renewable resource and nontoxic material) and poly(epichlorohydrin)-triol (PECH-triol) {a cross-linker}. After ultrasonication of the polyol blend with TiO2-TMP, through a one-pot synthesis, the mixture was made to...
