Abstract

Structural characterization of composite thin films composed of poly(vinyl alcohol) and a fluorocarbon amphiphile has been carried out. The wide-angle X-ray diffraction study revealed that the fluorocarbon amphiphile in the composite thin film forms bimolecular lamellae. The bimolecular lamellae were oriented parallel to the surface of the composite thin films. X-ray photoelectron spectroscopy showed enrichment of fluorocarbon groups on the surface of the composite thin film owing to the lower surface free energy of fluorocarbon groups compared with that of PVA. The surface of the composite film is completely covered with fluorocarbon amphiphilic molecules even when the weight fraction of fluorocarbon amphiphile is very small.
