Nanotribological Properties of Poly(ether ketone ketone) (PEKK) and Sulfonated Poly(ether ketone ketone) (S-PEKK) Thin Films

, 2002
An atomic force microscope (AFM) was used to determine the nanotribological properties of poly(ether ketone ketone) (PEKK) and sulfonated poly(ether ketone ketone) (S-PEKK) thin films, by sliding the AFM tip on the polymer surfaces and stepwise ...

Et lite pekk tesies

Nordlit, 2005
I det ytre er Vett og Uvett ei ganske lita bok, men den ruver som et storverk i nordnorsk litteratur. Og den har en posisjon i nordnorsk folkeliv og i nordnorsk bevissthet som ingen andre verdslige bøker har hatt - kanskje unntatt Nordlands Trompet. I det ytre ganske beskjeden, altså, men likevel et slags kulturelt landemerke, et fast punkt man som ...

Orbit Reconstruction with 3D Printed PEKK Implant [PDF]

Journal of Head and Neck Surgery, 2019
Alloplastic materials are used in facial bony reconstruction, but the ideal material for such procedures has yet to be elucidated. 3D printed polymers are a promising new material for use in bony reconstructive procedures. This article documents the novel usage of polyetherketoneketone (PEKK) in an orbital floor reconstruction.
