Abstract

The molecular aggregation states of poly(fluoroalkyl acrylate) [PFA-Cy, where y is the fluoromethylene number of the fluoroalkyl (Rf) groups] thin films were evaluated by in-plane and out-of-plane grazing-incidence X-ray diffraction (GIXD) measurements. It has been revealed that Rf chain of PFA-Cy with y≥8 was crystallized and formed ordered structures at the outermost surface. These results suggest that water repellent mechanism of PFA-Cy can be attributed to the presence of highly ordered R f chains. Poly(fluoroalkyl methacrylate)s with short Rf groups [PFMA-Cy, y≤4] thin films were also characterized. The receding contact angle of PFMA-Cy were lager than PFA-Cy with y≤4. This result suggested that the mobility of molecular chains was restricted by α-methyl groups and the reorientation of short Rf chains hardly ware occurred.
