本研究的目的是评估复合材料的剪切粘接强度PEKK通过应用与各种粘接材料相关的几种表面处理方法。将150个PEKK样本随机分配到15个组（n = 10），组合使用3种不同的表面处理（95%硫酸蚀刻、50 µm氧化铝的气载磨损和110 µm二氧化硅涂层氧化铝的气载磨损）和5种不同的粘合材料（Luxatemp Glaze & Bond，Visio.link、All-Bond Universal、Single Bond Universal和带Heliobond的Monobond Plus）。表面处理后，检查表面粗糙度和接触角。使用扫描电子显微镜评估表面处理后的地形变化。将树脂复合材料安装在每个试样上，然后进行剪切粘结强度（SBS）测试。使用双向ANOVA和事后Tukey检验对SBS数据进行统计学分析（P<0.05）。无论粘结材料，机械表面处理组产生了显着更高的剪切粘结强度值比化学表面处理组。与其他粘合剂不同，MDP和含硅烷的自蚀刻通用粘合剂（Single Bond Universal）显示出有效的剪切粘合强度，而与表面处理方法无关。机械表面处理在PEKK粘合方面表现更好。此外，自蚀刻通用粘合剂（Single Bond Universal）可以作为PEKK的替代粘合材料，无论表面处理方法如何。
The object of the present study was to evaluate the shear bonding strength of composite to PEKK by applying several methods of surface treatment associated with various bonding materials. One hundred and fifty PEKK specimens were assigned randomly to fifteen groups (n = 10) with the combination of three different surface treatments (95% sulfuric acid etching, airborne abrasion with 50 µm alumina, and airborne abrasion with 110 µm silica-coating alumina) and five different bonding materials (Luxatemp Glaze & Bond, Visio.link, All-Bond Universal, Single Bond Universal, and Monobond Plus with Heliobond). After surface treatment, surface roughness and contact angles were examined. Topography modifications after surface treatment were assessed with scanning electron microscopy. Resin composite was mounted on each specimen and then subjected to shear bond strength (SBS) test. SBS data were analyzed statistically using two-way ANOVA, and post-hoc Tukey's test (P<.05). Regardless of bonding materials, mechanical surface treatment groups yielded significantly higher shear bonding strength values than chemical surface treatment groups. Unlike other adhesives, MDP and silane containing self-etching universal adhesive (Single Bond Universal) showed an effective shear bonding strength regardless of surface treatment method. Mechanical surface treatment behaves better in terms of PEKK bonding. In addition, self-etching universal adhesive (Single Bond Universal) can be an alternative bonding material to PEKK irrespective of surface treatment method.
