Adhesion of Fluorinated UV-Curable Coatings to Functionalized Polyethylene

摘要

In this work we modified the surface of polyethylene in order to coat it with highly-fluorinated UV-curable coatings and assure good adhesion between the two polymers.Different methods were investigated, and a successful treatment was the grafting of a monomer containing a group able to dissociate under UV light. The surface modification was assessed by XPS, ATR-FT-IR and AFM analyses. The modified substrate was easily coated with the photocurable fluorinated formulation, and the highly hydrophobic and oleophobic layer formed after irradiation adhered well to the polyethylene substrate.
