Abstract

Acryl chemistry provides the convenience of manufacturing various functional polymers because of a lot of commercially available monomers and a facile polymerization method. In this study, novel fluorinated acrylic polymers with a benzotriazole pendant were successfully synthesized via radical polymerization. These polymers exhibited considerably high thermal stabilities and low surface energies because of fluorinated alkyl groups along with excellent optical properties owing to the presence of fluorinated alkyl groups and the intense UV absorption of the benzotriazole moiety (i.e., relatively low refractive indices), illustrating perfect UV-blocking performances of up to approximately 380 nm. Moreover, polymer-coated PET films exhibited high visible-light transmittance due to the antireflection in the interface between the PET substrate and the polymer film. The present benzotriazole-containing fluorinated acrylic polymers are expected to be used as UV-blocking organic coating materials, especially for organic solar cell applications.
