Simulated body fluid nucleation of poly(vinyl alcohol)/nanohydroxyapatitehydrogels

Polimery 2019, No 7-8, 487


DOI: dx.doi.org/10.14314/polimery.2019.7.3

Summary

Novel poly(vinyl alcohol) (PVA) andchitosan (CS) or 2-hydroxyethyl methacrylate (HEMA) and nanohydroxyapatite(nanoHAp) electrospinning-produced membranes were evaluated, in terms of theirbioactivity under exposure to simulated body fluid (SBF). After soaking them inSBF for 5, 8 and 15 days, the scanning electron microscopy (SEM) images showthe accumulation of calcium carbonate or calcium phosphate SBF on the surfaceof the nanohydroxyapatite (nanoHAp). This indicates that there might be anincreased bioactivity on the surface of the nanoHAp prepared by this method.
