Abstract

UV-curable polyurethane dispersions (UV–PUDs) have been reinforced with hydrophobic and hydrophilic modified silicas, respectively, and the effects have been studied with dispersion and dispersion cast films. It has been found that particle size increased and water swell decreased, tensile modulus, strength, and thermal stability increased with the addition and increasing amount of silica. These effects were more pronounced with the hydrophilic modified one than the hydrophobic modified one.
