“…In comparison with thermal curing, photocuring is a faster and less energy-consuming process and has been recently employed to obtain low surface energy films by Bongiovanni et al [8][9][10][11][12][13]. In most cases, they used a special fluorinated oligomer, perfluoropolyether, which is difficult to synthesize and mainly located in the middle of polymer main chains.…”

Low surface energy polymeric films from partially fluorinated photocurable solventless liquid oligoesters

We have recently shown that low surface energy polymeric films can be readily obtained from partially fluorinated hydroxyl-end-capped solventless liquid oligoesters by thermal curing [1]. Photocurable liquid oligoesters can be prepared by further substituting the remaining hydroxyl end groups with acrylic double bonds. A conventional photoinitiator containing 2-hydroxy-2-methylpropiophenone was used to cure the liquid oligoesters. As the fluorine content increases from 0 to about 1.57 wt %, the surface energy decreases by about 14 mN/m. The fluorine level in the outer few nanometers is significantly greater than that in the bulk, as revealed by XPS studies. The driving force for the surface segregation of fluorinated species comes from the large difference in surface energy between the oligoesters and their fluorinated counterparts.

“…The results on glass and steel agreed with previously reported data showing that fluorinated groups could migrate to the air-monomer surface and could form highly oriented layers with low surface energy. 25 However, the orientation of the fluorinated moieties was strongly influenced by the substrate used, with maximum effects for those that interacted strongly with the carboxylic acid groups.…”

ABSTRACT:The synthesis, characterization, and polymerization of a perfluoroalkyl ether substituted methacrylic acid (C8F7) were investigated. C8F7 was photopolymerized at different temperatures, higher double-bond conversions being achieved at higher polymerization temperatures. The polymerization rates were fast in comparison with those of typical methacrylate esters. Thermogravimetric analysis of the obtained polymers showed thermal stabilities up to 270 -290°C. The initial degradation at 200°C involved the loss of water and the partial loss of the perfluoroalcohol via the intramolecular formation of anhydride and lactone groups. The surface properties of coatings obtained with C8F7 coatings on various substrates were evaluated with water and hexadecane contact-angle measurements, which confirmed that low-surface-energy polymeric coatings were obtained.
