Hybrid organo-inorganic composite materials of incorporative type based on calcium phosphates for bone surgery

Abstract

Proposed is a concept for the obtaining of a hybrid organo-inorganic composite material of incorporative type with a binder based on sevilen and an inorganic filler based on nanoparticles of Ca3(PO4)2 nanoparticles. The binder simultaneously contains two different phases: α- and β-·modifications of Ca3(PO4)2 separated by a coherent boundary. It is shown that during the formation of the composite severol processes occur simultaneously. They ore: partial hydration of α- Ca3(PO4)2, partial hydrolysis of sevilen. as well as intermolecular structuring due lo the formation of chelate complexes. Studied is the effect of the composition. structure, the ratio of initial components on the proper ties of the composite.
