通过准分子激光辐照聚醚醚酮（PEEK）表面引起的改性已被调查的激光工艺参数的函数的激光能量密度低于材料烧蚀阈值。在193 nm激光处理的情况下，由于在表面上形成新的极性和反应性基团，PEEK的粘附性能显著增加。必须控制这些反应性基团的程度，因为它们以高浓度存在也可能对经处理表面的机械性能具有负面影响。使用248 nm辐射的激光处理没有导致PEEK的粘附性能显著增加。这可能是由于在该激光波长下表面的热降解。
The modifications induced by excimer laser irradiation of poly(ether ether ketone) (PEEK) surfaces have been investigated as a function of the laser process parameters for laser fluences below the material ablation threshold. In the case of 193 nm laser treatment, a significant increase in the adhesion properties of PEEK was obtained due to the formation of new polar and reactive groups on the surface. The extent of these reactive groups has to be controlled since their presence in high concentration may also have a negative effect on the mechanical properties of the treated surface. Laser treatments using 248 nm radiation did not result in a significant increase in the adhesion properties of PEEK. This probably results from thermal degradation of the surface at this laser wavelength.
