Hemocompatibility and Surface Morphology of Vegetable Oil Based Polyurethane Eggshell Powder Nanocomposite

In the present work, biocompatible polyurethane (PU) and PU – based nanocomposites (PUENs) of different composition have been synthesized from hydroxylated olive oil- based polyurethane and eggshell powder as filler. The synthesized polyurethane nanocomposites are characterized by FT-IR spectroscopy, SEM and XRDanalysis. The chemical resistance and biodegradability of the PUENs have been studied in different chemical environments. SEM analysis confirms the incorporation of eggshell powder into the polyurethane matrix. TheXRD study reveals that the intensity of the peak increases from 90 to 137 cts with the increase in crystallinity. The chemical resistance shows the swelling and degradation of the PUENs at higher concentration of the HCl and NaOH. Insoil burial degradation method 13 %-18% of weight loss is observed in PUEN3 and PUEN4. The hemolytic rate of PUEN4 is <2% at 10 to 40µg/ml showing non-hemolysis, implies better hemocompatibility of the sample.
