Abstract
Nanoclay, Cloisite 20A, in 0, 0.5, 1, 2 and 3 w% were dispersed by mechanical and Ultra sonic mixing method in polyester-ether vehicle in the same conditions. Then solvent free aromatic isocyanate hardener was added in the above specimens stoichiometrically in order to synthesize nanocomposites. The X-Ray Diffraction (XRD) analysis and Transmission Electron Microscopy (TEM) indicate that the nanoclay has intercalated in the 100% Solid Polyurethane. Results of Dynamic Mechanical Thermal Analysis (DMTA) show that nanoclay content increases the thermal transition (Tg) for nanocomposite specimens, while the storage modulus decreases due to decrease of cross linking density of nanocomposites.
