This study attempted to prepare polyimide coatings (PIs) containing 6FDA (hexafluoroisopropylidene diphthalic anhydride) and/or NTDA (1,4,5,8 naphthalenetetracarboxylic dianhydride) in various ratios. 1% of these polyimide chains were terminated with 1H,1H-perfluorooctylamine (PFOA) and PFOA, and terminated polyimide coatings (PIFs) were prepared in the same ratios as PIs. Coatings were produced on aluminum substrates by a 75-μm wire-wound applicator and thermally imidized. Finally, thermal, wea...

In this study fluorine chains were bonded with covalently in epoxy acrylate system via UV light. For this purpose, five different coating samples prepared. Bisphenol-A glycerolate diacrylate (epoxyacrylate) and 1,6-Hexanediol diacrylate were used as main coating solution. The weight ratio of Bisphenol-A glycerolate diacrylate and HDDA was calculated as 7/3. As a long fluorine chain, 1 H ,1 H ,2 H ,2 H -perfluorodecyl acrylate (PFOA) was added into the main coating solution in the ratios of 0.25 ...
