Self-segregation behavior of N-ethyl-pentadecafluorooctanamide-terminated polybutylene isophthalate and its effects on film morphology and wettability.

Abstract

Polybutylene isophthalates (PBI) end-capped with N-ethyl-pentadecafluorooctanamide were synthesized from dimethyl isophthalate, 1,4-butanediol, and N-(2-hydroxyethyl)-perfluorooctanamide with fluorine monomer content from 0 to 5 mol %. The results demonstrated that there was an obvious gradient drop of fluorine concentration from the film surface down to… (More)
