Abstract

Abstract : A selective modification of the surface properties of UV‐cured epoxy films was achieved, with an important enhancement of hydrophobicity and scratch resistance, by dispersion on the UV‐curable formulations of fluorinated functionalized silica particles. The photopolymerization process was investigated and the films were fully characterized. Contact angle measurements with water on UV‐cured films showed a linear increase of the contact angle of cross‐linked films by increasing the functionalized SiO2 content in the photocurable formulation. Also, a consistent and linear improvement of penetration resistance was noted in terms of penetration depth by increasing the fluorinated functionalized silica content.
