Description

The surface state of polyvinylalcohol (PVA) films improved by three perfluorocarbonyl chlorides (CnF2n+1COCl; n=4, 6, and 8) has been studied in terms of three surface tension components: London dispersion force, polar force, and hydrogen bonding force.<BR>London dispersion and hydrogen bonding forces were smaller for PVA films treated with perfluorocarbonyl chlorides than for untreated PVA films.<BR>Water repellent and lipophobic properties of PVA films increased with increasing perfluoroalkyl chain length in the chemicals.
