| Popis: | Simple, reactive amphiphilic molecules were prepared by condensation of perfluorooctylethyl alcohol with elaidic, oleic, and linoleic acids. The fluorinated, unsaturated esters were found to be surface active in polyester and urethane-modified alkyd coatings. In addition, they function much like typical drying oils used in these coatings through oxidative cross-linking. The surfaces of the coatings were examined by contact angle goniometry and X-ray photoelectron and time-of-flight secondary ion mass spectroscopy. The solution properties of these fluorinated derivatives were studied by measurement of surface tension isotherms, vapor pressure osmometry, and variable temperature 19F NMR spectroscopy in n-butyl acetate solution. Analysis of the data revealed that aggregation is occurring at low ( |
