Electrospun polyurethane based nanocomposite scaffolds were fabricated by mixing with indhulekha oil. Scanning electron microscope (SEM) portrayed the nanofibrous nature of the composite and the average diameters of the composite scaffold were smaller than the pristine scaffolds. The fabricated scaffold was found to be hydrophobic (114°) due to the inclusion of indhulekha oil, which was displayed in contact angle measurement analysis. The fourier transform infrared spectroscopy (FTIR) results indicated that the indhulekha oil was dispersed in PU matrix identified by formation of hydrogen bond and peak shifting of CH group. The PU/indhulekha oil nanocomposite exhibits a higher decomposition onset temperature and also residual weight percentage at 900°C was more compared to the pure PU. Surface roughness was found to be increased in the composite compared to the pristine PU as indicated by the atomic force microscopy (AFM) analysis. In order to investigate the blood compatibility of electrospun nanocomposites the activated partial thromboplastin time (APTT) assay, prothrombin time (PT) assay and hemolytic assay were performed. The blood compatibility results APTT and PT revealed that the developed nanocomposites demonstrated delayed clotting time indicating the anticoagulant nature of the composite in comparison with the pristine PU. Further, it was also observed that the hemolytic index of nanocomposites was reduced compared to pure PU suggesting the non-hemolytic nature of the fabricated scaffold. Hence, the fabricated nanocomposites might be considered as a potent substitute for scaffolding damaged tissue due to their inherent physicochemical and blood compatibility properties.
