Quasi-living surface graft polymerization with phosphorylcholine group(s) at the terminal end.

Abstract:

:A surface graft polymer with one or two phosphorylcholine (PC) polarheads at the terminus of the growing chain end was prepared by sequential reactions on a glass substrate. The dithiocarbamate group covalently bound to glass surfaces was derivatized with one or two PC groups and then irradiated with ultraviolet light in the presence of N,N-dimethylacrylamide (DMAAm). X-ray photoelectron spectroscopy, wettability measurements and dye staining experiment for the PC group showed that the resultant graft copolymers were produced via iniferter-based quasi-living radical polymerization, in which the polyDMAAm graft chain contains one or two PC groups at the terminal end of the graft chain. These polymer surface grafts may help provide biocompatibility.

  • Constitutive models for impacted morsellised cortico-cancellous bone.

    abstract::Constitutive models are developed, based on the results of confined compression testing, to describe the visco-elastic, and non-linear elasto-plastic behaviour of morsellised cortico-cancellous bone (MCB). It is found that the elastic modulus, E of MCB can be expressed as a linear function of the applied pressure, p. ...
