Synthesis and Characterization of Mixed Ligand Complexes of Zirconium(IV) with Sulphur, Nitrogen and Oxygen Donor Ligands

A new route to synthesize new nanosized mixed ligand complexes of Zr(IV) have been investigated by the reaction of zirconium(IV) chloride with 3(2'-hydroxyphenyl)-5-(4-substituted phenyl)pyrazolines and ammonium salts of dithiophosphate, which after being treated with H2S gas acts as a precursor for ZrS2. These complexes have been examined for crystalline/amorphous nature through XRD. The morphology of the complexes was studied by employing XRD which shows that all the complexes are amorphous solid.

Viscoelastic Properties of Amine-Cured Epoxy-Titania Composites Obtained by the Sol-Gel Method

Viscoelastic properties of amine-cured epoxytitania composites were investigated. The composites were synthesized by the sol-gel method and analysis of their physico-mechanical properties indicated that higher TiO2 content causes the decrease in glass transition temperature of the composites. Non-linear change of crosslink density with a filler content was observed.
