A series of waterborne polyurethane (WPU) was synthesized using polycaprolactone diol and 4,4’- methylene dicyclohexyl diisocyanate as the main domains of urethane, dimethylol butanoic acid as the anionic internal emulsifier and trimethylamine as the neutralizing agent. Castor oil was also added to confirm the change in the physical properties of WPU according to the presence and molecular weight of castor oil and maximize the biodegradability and biocompatibility of the WPU series made in this way. WPU was designed to increase bio-adhesion because castor oil increases the total molecular weight of the WPU, which increases the crosslinked structure. As a result, mechanical properties were improved, and biodegradability evaluation using the effect of the bio-enzymes was thoroughly analyzed through field emission scanning electron microscopy. WPU made through the above experiment has excellent physical properties and is biodegradable by bio-enzymes. Therefore, it is environmentally friendly and can be a promising candidate in various biofields.
