Polyetheretherketone in Orthopedic Plate Design to Facilitate Fracture Recovery

Journal of Biomechanical Science and Engineering, 2011
Polyetheretherketone (PEEK) is becoming an interesting alternative to titanium alloys and stainless steel in orthopedics. This study compares two types of PEEK fracture plates (natural and carbon reinforced) with titanium plates of the same design ...

High Modulus, Strut-like poly(ether ether ketone) Aerogels Produced from a Benign Solvent

Gels
Poly(ether ether ketone) (PEEK) was found to form gels in the benign solvent 1,3-diphenylacetone (DPA). Gelation of PEEK in DPA was found to form an interconnected, strut-like morphology composed of polymer axialites.
