Abstract
Polymeric films with surface energies as low as 10 mN/m were prepared from a mixture of a hydroxyl-end-capped solventless liquid oligoester (SLO), a blocked polyisocyanate, and a novel fluorinated blocked isocyanate (FnB-NCO; the ratio of the fluorinated tail and the caprolactam blocking group: 1:1), with less than 4 wt % of fluorine in the films. The curing temperature demonstrated a significant effect on the reaction rate and the film wettability: a higher curing temperature led to a less significant surface enrichment of fluorine, especially at a low F content (
