Biocompatible waterborne polyurethanes (B-WPUs) were successfully prepared using polycaprolactone diol (PCL) and 4,4'-Methylene dicyclohexyl diisocyanate (H12MDI) as soft segment of prepolymer, dimethylolbutanoic acid (DMBA) as emulsifier, and trimethylamine (TEA) as neutralizer, ethylenediamine (EDA) as chain extender based on different molecular weight of pre-polymer. Various properties to apply as bio-adhesives of wound closure were studied through FT-IR, DSC, TGA, contact-angle, and UTM. Biodegradation efficiencies by natural enzyme were also evaluated using degrading-enzyme systems, as a function of time. B-WPU could be considered as a promising candidate to be applied the various bio-fields where biodegradation is important. |
