Surface fluorination of PEEK film by selective wet-chemistry

Primary tabs

Marchand-Brynaert, Jacqueline [UCL] Pantano, G Noiset, O.

The PEEK-OH film, obtained by surface reduction of the native PEEK him, was designed as a versatile key-intermediate for the development of mild and selective fluorination processes. Reaction with diethylaminosulfur trifluoride in CFCl3, and 4-trifluoromethylbenzamide in HOAc (H2SO4 catalysis) gave the PEEK-F and PEEK-PhCF(3) films, in 92% and 36% yields, respectively. Reaction of PEEK-ONa with heptadecafluoro-10-iododecane in DMF produced the PEEK-C8F17 film in 6% yield. The modified PEEK surfaces were analysed by X-ray photoelectron spectroscopy (X.p.s.).
