摘要：

In blends of poly(ethyl acrylate) (PEA) and poly(vinylidene fluoride-co-hexafluoroacetone) [P(VDF-HFA)], surface segregation of the P(VDF-HFA) component was confirmed by X-ray photoelectron spectroscopy. The PEA/P(VDF-HFA) blends exhibited lower critical solution temperature phase behaviour, with a critical temperature of 150 degrees C. Since the surface tension value of P(VDF-HFA) is lower than that of PEA, this may influence surface segregation behaviour in PEA/P(VDF-HFA) blends. Surface segregation results of the PEA/P(VDF-HFA) blends are compared with those from a previous study on immiscible acrylate copolymer/fluoro copolymer blends.
