In this study, aqueous polyurethane dispersion (PUD) is synthesized using poly[tetramethylene glycol] (PTMG) as soft segment, isophorone diisocyanate (IPDI) and dimethylol propionic acid (DMPA) as hard segment. Also, polyurethane/graphene nanocomposites are prepared by adding thermal reduced graphene oxide into PUD. The nanocomposites are versatile and environmentally friendly coating materials that are available in a wide range of hardness and solid content. The degree of graphene dispersion in the nanocomposites was investigated using XRD. Electrical conductivity were measured by digital multimeter and the physical and thermal properties were examined through UTM and DSC. |
