A perfluoro polyisophthaloylester (PF-oate-Iso-R) has been synthesized via Scotthen-Baumann reaction of isophthaloyl chloride with different perfluoro alcohols in the presence of a triethylamine in methyl ethyl ketone (MEK). PF-oate-Iso-R was characterized using 1H, 13C NMR, FT-IR, TGA and DSC. In order to fabricate low wettable coatings, PF-oate-Iso-R were blended with PET in different ratios and deposited on Si wafers. The morphology of the coatings was characterized by AFM . In addition, the wettability of the coatings was determined by contact angle measurements of both water and hexadecane . It was found that the wettability of coatings reduced with increasing the amount of PF-oate-Iso-R in coatings.
