Synthesis and Investigation of Surface Chemistry of ZwitterionicPolyurethane Coatings

Unwanted adhesion and deposition of biological materials such as macromolecules, proteins, bacteria,and microorganisms on surfaces pose significant challenges in various applications. Zwitterionicpolyurethanes are introduced as a new generation of antifouling coatings, offering tunable mechanicaland chemical properties. In this study, thermoplastic and thermoset polyurethanes based on ionizablediols were synthesized using a two-step dropwise method. Positive and negative charges weredistributed separately and uniformly within the polyurethane structure. Furthermore, the contact angleand water uptake investigations underscored the potential of zwitterionic polyurethanes to reduceadhesion and enhance antifouling properties.
