Preparation and Properties of Weldable Self-Cleaning PVDF/PVC Blended Film

Abstract:

Article Preview

PVDF was blended with PVC to improve the weldable property of PVDF topcoat. Effects of film formation process on the surface properties of PVDF/PVC blended film were investigated. Peeling strength of PVDF/PVC blended film has reached the internationally accepted standards (144.3N/5cm) when PVC concentration was 30%. Based on the “lotus effect” principle, PVDF/PVC film was hydrophilic modified by alkali solution and then grafted with alkyl chlorosilane to fabricate the micro- and nano-structures as the surface of lotus leaf. After grafting, contact angle of PVDF/PVC blended film was as high as 152.8°, and self-cleaning test showed dusts on this film surface can be easily taken away by water droplet when PVDF/PVC blended film was titled less than 1°.
