Preparation and characterization of fluorinated acrylic pressure sensitive adhesives for low surface energy substrates

In this work, a series of PSAs with various fluorinated groups were synthesized using 2,2,3,4,4,4-hexafluorobutyl acrylate (F6BA) via solution polymerization. Compared to existing PSAs, fluorinated acrylic PSAs exhibited excellent performance in terms of the adhesiveness to the low surface energy materials. F6BA played a positive role in heat resistance of PSAs, resulting from the improvement of decomposition temperatures of PSAs substantially due to the addition of fluorinated groups. FT-IR and DSC results indicated that fluorinated groups were introduced to the structure of copolymer successfully and all the monomers were well copolymerized. Furthermore, it was confirmed that the incorporation of fluorine improved wettability of PSAs effectively and extended protective property of PSAs against the water corrosion. (C) 2015 Elsevier B.V.
