Abstract
Methods of preparing waterborne polyurethane dispersions involving reacted units of a polyol, an acidic diol, a hydroxy functionalized polyhedral oligomeric silsesquioxane, a diisocyanate, and a chain extender. Polyurethane coatings based on these waterborne polyurethane dispersions are evaluated on their hydrophobicity (water contact angle), mechanical strength (e.g. tensile strength, Young's modulus, elongation at break), and antifouling properties.
