The present invention relates to a modified polyaryletherketone polymer (PAEK) with chemically modified surfaces with azides, alkynes, thiols, maleimides, sulfonylazides or thio acids, suitable for "click" reactions and to a process to obtain it. It also relates to the conjugated biomaterials derived thereof, PAEK type materials with surfaces modified with a RGD (Arg- Gly-Asp) and/or OGP10-14 (Tyr-Gly-Phe-Gly-Gly) peptidomimetics and to a process to obtain it. These materials are particularly useful for manufacturing medical devices. Finally, the present invention also relates to a fluorescent PAEK material.
