The present invention provides modified polyaryl ether ketones (PAEK)s having fluorinated moieties incorporated therein. The present invention also relates to a method for covalently attaching fluorinated moieties onto the surface of PAEK, said method comprising reducing the ketone groups of the PAEK to hydroxyl groups to obtain a modified PAEK and then reacting the hydroxyl groups with a compoundbearing a fluorinated moiety. 本发明提供了其中掺入了氟化部分的改性的聚芳醚酮(PAEK)。本发明还涉及一种用于将氟化部分共价附接到PAEK表面上的方法，所述方法包括将PAEK的酮基还原为羟基以获得改性的PAEK以及然后使羟基与带有氟化部分的化合物反应。
