A novel fluorinated polyurethane (FPU) with fluorine-containing pendent groups was prepared by using fluorinated polyether glycol (PTMG-g-HFP) as a soft segment,1,6-hexamethylene diisocyanate (HDI) or toluene diisocyanate (TDI) as a hard segment and 1,4-butanodiol (BDO) as a chain extender.FTIR,¹H NMR,¹³C NMR and GPC were used to characterize the structure of the fluorinated polyurethane.Thermal stabilities of the fluorinated polyurethane and the corresponding hydrogenated polyurethane were studied by TGA.XPS analysis at two different sampling depths for the fluorinated polyurethane was used to investigate the surface compositions of FPU.The results showed the fluorine enrichment on the surface of FPU.
