Morphology Properties of Polyurethane/Clay Nanocomposites Base on Palm Oil Polyol Paint

An organically modified clay and a pristine clay were used to prepare biodegradable thermoplastic polyurethane (PU) paint/clay nanocomposites. In this paper, polyurethane paint /clay nanocomposites base on palm oil polyol were prepared by isocyanate, polyol and organoclay (a clay modified with Cetyl trimethyl ammonium Bromide (CTAB) and Octadecylamines (ODA). The morphologies of samples were revealed by transmission electron microscopy (TEM) and Intercalation of PU into clay galleries and crystalline structure of PU were investigated using X-ray diffraction (XRD). The morphology of the resulting composite showed a combination of intercalated and partially exfoliated clay layers with occasional clay aggregates
