We have prepared biocompatible composites of 80 wt% polyvinyl alcohol (PVA)-(20 wt%) polyvinylpyrrolidone (PVP) blend with different concentrations of bioactive nanohydroxyapatite, Ca-10(PO4)(6)(HO)(2) (HAP). The composite films demonstrated maximum effective conductivity (sigma similar to 1.64 x 10(-4) S/m) and effective dielectric constant (epsilon similar to 290) at percolation threshold concentration (similar to 10 wt% HAP) at room temperature. These values of sigma and s are much higher than those of PVA, PVP or HAP. Our preliminary observation indicated excellent biocompatibility of the electrospun fibrous meshes of two of these composites with different HAP contents (8.5 and 5 wt% within percolation threshold concentration) using NIH 3T3 fibroblast cell line. Cells viability on the well characterized composite fibrous scaffolds was determined by MIT [3-(4,5-di-methylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay analysis. Enhancement of sigma, due to HAP addition, was found to show increased biocompatibility of the fibrous scaffold. Enhanced sigma value of the PVA/PVP-HAP composite provided supporting cues for the increased cell viability and biocompatibility of the composite fibrous meshes. Excellent biocompatibility these electrospun composite scaffolds made them to plausible potential candidates for tissue engineering or other biomedical applications. (C) 2016 Elsevier B.V.
