“…The strong bonding of VUV treated samples was considered to be owing to the surface modified hydrate bridge layer, which increased the bondability of these heterogeneous materials. Up to our knowledge, it is the first time that a PEEK-metal direct bonding at low temperature was evaluated in literature, and these results can be comparable with other PEEK-based direct bonding, such as autohesion bondings [7].…”

A direct hybrid bonding of PEEK-Pt is feasible at low temperature of 150 ºC through surface treatment technologies of vacuum ultraviolet (VUV) and fast atom bombardment (FAB). The X-ray photoelectron spectroscopy showed the VUV treatment was capable of creating hydrate bridge layers on both PEEK and Pt surfaces, which were considered to form a robust bond through dehydration reactions. Shear strength test showed that the VUV-treated samples were stronger than the FAB-treated ones, and the highest strength reached 0.91 MPa, which was comparable with conventional PEEK-based direct bondings. This technology is expected to be applied in future body implantable medical micro electromechanical system devices.

“…Whereas in this experiment there was obtained a value 1.6 μm ( Table 1) and this is the highest value of roughness. Investigating the PEEK surface structure using the SEM technique Zhang et al [45] noticed that this polymer exhibits fiberlike structures and cavities with depressions which are similar to those in Figure 2. Roughness on the plasma-treated surface becomes more of a nano-micro character.…”

Wettability properties of polyetheretherketone (PEEK) activated and non-activated by nitrogen plasma have been investigated. Moreover, the PEEK plates were covered with antibacterial chitosan and its wettability properties were also investigated. Surface topography was determined using SEM and optical profilometry and surface composition by FT-IR and XPS. For determination of apparent surface free energy, the hysteresis approach (CAH), acid base (LWAB), and Owens-Wendt (O-W) theory were used. The equilibrium contact angles were calculated from the Tadmor theory and further used for apparent surface energy calculation applying the abovementioned approaches. Due to the surface plasma activation both the roughness of the surface and the polar component of apparent surface free energy increased. It is shown that nitrogen plasma activation of PEEK surface increases the adhesion of chitosan to the surface due to the combination effect of: (i) the increase in surface roughness, (ii) introducing the polar groups onto the surface.

“…Zhang et al [17] and Comyn et al [18] have shown that PEEK when treated with oxygen plasmas have shown improved adhesion through the introduction of oxygen functional groups (C-O) such as hydroxyl groups on the surface when the surface interacts with radicals within the oxygen plasma.…”
