Evaluation of the Bond Strength of Polyetherketoneketone to Dental Ceramic.
The journal of adhesive dentistry, 2022 To evaluate the efficacy of different surface treatments on the bond strength of polyetherketoneketone (PEKK) to ceramic materials.PEKK test specimens were separated into four groups according to surface treatments (group S: sandblasting; group A: acid etching; group SA: sandblasting + acid etching; group C: control).

Thermal conductivity and diffusivity of carbon‐reinforced polyetherketoneketone composites [PDF]
Journal of Applied Polymer Science, 2019 ABSTRACTHeat transfer properties play an important role in processing of polyetherketoneketone (PEKK)/carbon fiber (CF) composites. Accordingly, thermal conductivity and diffusivity of PEKK, PEKK/glassy carbon (GC), and PEKK/CF composites have been studied. Observed increase in conductivity and diffusivity with carbon filler addition was analyzed using
