用衰减全反射红外光谱(ATR-FTIR)及~(13)C-NMR方法研究了聚醚醚酮(PEEK)在浓硝酸中的反应。发现PEEK在浓硝酸中发生硝化并有轻度的氧化发生,结晶PEEK比无定形PEEK具有更优异的耐腐蚀性。
The reaction of polyetheretherketone (PEEK) in concentrated nitric acid was studied by attenuated total reflectance infrared spectroscopy (ATR-FTIR) and ~ (13) C-NMR. It was found that PEEK was nitrated in concentrated nitric acid and mild oxidation occurred. Crystalline PEEK had more excellent corrosion resistance than amorphous PEEK.
