We have successfully synthesized two high-performance polys, 6F-PEEK and m-TPEEK.

但无定形区的老化并不能从根本上影响较高结晶度的PEEK的结晶行为，无定形区的总量没有明显变化。

In this bath, maleic acid was an inhibitor, when its concentration was kept at 20 mg/L, the deposition rate could reduce to 6.17μm/h, the content of nickel decreased to 1.74% and the resistivity was 7.51μΩ·cm; Potassium ferrocyanide inhibited deposition of copper, when its content was 0.5 ppm, the deposition rate decrease to 3.38μm/h, the content of nickel was 2.03%, the resistivity can reduced to 5.41μΩ·cm, the copper deposits also had higher (111) plane orientation. Thiourea was also an inhibitor in this system, when its concentration was kept at 0.8 ppm, the deposition rate was 4.72μm/h, the content of nickel in the film was 1.20%, the resistivity can reduced to 5.46μΩ·cm, at the same time, the deposition at (111) plane orientation become more favorable.
