| Abstract Scope |
Owing to its superior bulk mechanical properties, poly (ether ether ketone)
(PEEK) has gained popularity over the past 15 years as a metal substitute in
biomedical implants. Low surface energy is a fundamental issue with PEEK
implants. This low surface energy caused by a moderately hydrophobic surface
may be able to inhibit cellular adherence and result in the development of an
inflammatory response, which may result in cell necrosis and apoptosis. In
this work, plasma and ozone treatments have been utilized to surface activate
PEEK and graft ionic bioactive polymer polyNaSS (poly (sodium styrene sulfonate)) successfully on the surface to promote cellular attachment and
biomineralization. The main goal of our research has been to find a
stable green process for surface modification of PEEK by plasma/ozone approaches to increase PolyNaSS grafting efficiency and biomineralization. |
