Abstract :
PVA/HAp nanocomposites of varying composition for biomaterial applications have been synthesized. The PVA/HAp nanocomposite materials were characterized by XRD, FTIR, 31P NMR, TGA, DTA and FESEM. Hydroxyapatite(HAp) nano rod embedded composite was prepared using poly (vinyl alcohol) (PVA) as a matrix with different weight percentages (wt %). The results indicated that the size and crystallinity of HAp nano particles decreases with increase in PVA concentration in the composite. SEM confirms the presence of HAp nano rod crystals in PVA matrix. PVA/HAp nano composites were screened for antimicrobial activity.
