Mechanical and biological characteristics of diamond-like carbon coated poly aryl-ether-ether-ketone.
Poly aryl-ether-ether-ketone (PEEK) is an alternative to metal alloys in orthopedic applications. Although the polymer provides many significant advantages such as excellent mechanical properties and non-toxicity, it suffers from insufficient elasticity and biocompatibility. Since the elastic modulus of diamond-like carbon (DLC) is closer to that of cortical bone than PEEK, the DLC/PEEK combina...
متن کاملGlucose-cored poly(aryl ether) dendron based low molecular weight gels: pH controlled morphology and hybrid hydrogel formation.
We designed poly(aryl ether) dendron based transparent hydrogels containing glucose moiety, which undergoes in situ transition from nanofibers to spherical aggregates, upon pH variation. The process is reversible and the assembled structures have been characterized by DLS and SEM. More importantly, efficient dispersion of graphene oxide results in lower CGC (0.08 wt%) value and higher mechanica...
متن کاملComparison of osteogenic potential of poly-ether-ether-ketone with titanium-coated poly-ether-ether-ketone and titanium-blended poly-ether-ether-ketone: An in vitro study
STATEMENT OF PROBLEM Poly-ether-ether-ketone (PEEK), a high-performance semi-crystalline thermoplastic polymer, has been employed to replace the metallic implant components in orthopedics. There were various studies performed in accordance to medical grade PEEK, but the relationship between titanium dioxide (TiO2)-coated PEEK, TiO2-blended PEEK, and untreated PEEK still remains complicated, eve...
متن کاملSynthesis, fluorescence and photoisomerization studies of azobenzene-functionalized poly(alkyl aryl ether) dendrimers.
A series of azobenzene-functionalized poly(alkyl aryl ether) dendrimers have been synthesized and their photochemical and photophysical properties in solution and as thin films have been investigated. Although the photochemical behavior of the azodendrimers in solution indicated that the azobenzene units behave independently, very similar to the constituent monomer azobenzene unit, the properti...
متن کاملLaser Light-Scattering Study of Novel Thermoplastics. 1. Phenolphthalein Poly(aryl ether ketone)
Five different molecular weight phenolphthalein poly(aryl ether ketone) (PEK-C) fractions in CHCl3 were studied by static and dynamic laser light scattering (LLS). The dynamic LLS revealed that the PEK-C samples contain some large polymer clusters. These large clusters can be removed by filtering the solution with a 0.1-μm filter. We found that the persistence length of PEK-C in CHCl3 at 25 °C ...
