Abstract Details

2018, Master of Science, University of Akron, Polymer Science.
Polyurethanes exhibit excellent mechanical properties due to the presence of alternating hard segments and soft segments, and they have been extensively used for various biomedical applications. However, medical devices made from traditional polyurethanes typically have hydrophobic surfaces that are not lubricious or not able to resist non-specific protein adhesion, which limited their applications. To address this situation, in this work, we modified the composition of Pellethane and Tecoflex, two commercial thermoplastic polyurethanes (TPU), with hydrophilic functionalities on the side chain through copolymerization with hydrophilic amine derived N-substituted diols or grafting to modification via esterification reaction using hydrophilic polymer such as polyethylene glycol (PEG). The synthesis and characterization of these grafted polyurethanes will be discussed. Our results showed that such modifications provide a more hydrophilic material, as evidenced by the decreased water contact angle compared to the non-functionalized Pellethane and Tecoflex.
