| dc.description.abstract | Glass/polymer composites can mimic the natural structure of bone by possessing a fibre-matrix configuration which provides appropriate physical and biological properties. Wollastonite ceramics are known for their promising bioactivity and biocompatibility when applied in bone regeneration. Polyvinyl alcohol (PVA) has various attractive properties including biocompatibility and degradability which may be exploited as a polymer matrix in composites for biomedical applications. Therefore, a cost–effective method of preparing wollastonite/PVA composites is desirable by starting from bentonite clay as silica source for the glass, instead of traditional alkoxysilanes. Results obtained revealed for the composite a compressive strength of 0.3 MPa, the ability to induce apatite on its surface when immersed in simulated body fluid (SBF) for 7 days, and exhibited desirable controlled degradation. Оur method can be up-scaled for preparation of wollastonite/PVA composite commercially for possible use in bone regeneration. | en_US |
