Environmentally friendly waterborne polyurethane dispersions (PUDs) are widely used in many application such as biodevices, optoelectronics, coatings and adhesive due to excellent chemical resistance, water resistance and strength. PUDs can exhibit various physical properties depending on the types of the polyol, diisocyanate, and chain extender. Recently, graphene oxide (GO) was employed in many industry and which is well dispersed in water and organic solvents because it has an oxygen functional group. In this study, PUD/GO nanocomposites were prepared by using polycarbonate diol and aliphatic IPDI and the thermal and mechanical properties of WPU/GO nanocomposites were investigated using dynamic mechanical analysis (DMA), universal testing machine (UTM), differential scanning calorimeter (DSC), Fourier transform infrared spectroscopy (FTIR). |
