Synthesis and characterization of poly(4-vinyl pyridine-co-styrene)/FHAP nanocomposite, and its biomedical application

Among the composite materials, ceramic/polymer possesses significant advantages of high mechanical reliability and excellent biocompatibility for applications in load-bearing areas. In this work, PVPCS(Poly (4-vinyl pyridine-co-styrene))/FHAp nanocomposites of varying weight percentages were synthesized and characterized physical-chemically by XRD, FTIR, 31P NMR, TGA, DTA, and FE-SEM and biologically by antimicrobial and anti-inflammatory assays for evaluating their potential use for biomedical applications. The results indicated that the size and crystallinity of FHAp nanoparticles decrease with increase in PVPCS concentration in the composite. SEM confirmed the presence of FHAp nano rod crystals in PVPCS matrix. The nano PVPCS20/FHAp demonstrated the highest antifungal and antibacterial activity and favorable inhibition of human cell hemolysis. The designed PVPCS/FHAp nanocomposites constitute promising candidates for biomedical applications.
