Waterborne polyurethane (WPU) was synthesized using castor oil-based polyol, petroleum-based polyol, and isophorone diisocyanate. The crosslinking of WPU was obtained by the allophanate reaction of excess diisocyanate. The crosslinked WPUs were characterized by FT-IR, DSC, TGA, contact-angle, and UTM. Their biodegradations were analyzed thorough the effect of enzyme in the samples morphology. The crosslinked WPU could be considered as a promising candidate to be applied the various bio-fields because of the possibility of their synthesis as prepolymers and therefore their reaction with amino groups present in the biological molecules. |
