Abstract In this research, a tannic acid-modified tin oxide along with newly synthesized polyamide<br />was used as reinforcing and anti-migration of plasticized poly(vinyl chloride)<br />(p-PVC). Tin oxide nanoparticle was modified with tannic acid as a biobased<br />and safe compound. The modified tin oxide was used as a reinforcement of p-PVC.<br />Then, a fully aromatic polyamide was synthesized as the coating agent of the p-<br />PVC. PA was used for its additional properties such as excellent mechanical strength<br />and anti-migration properties. Characterization, morphology, mechanical properties,<br />and blood compatibility of this nanocomposite system were done by means of<br />attenuated total reflectance–Fourier transform infrared spectroscopy, X-ray diffraction,<br />field-emission scanning electron microscopy, migration analysis, tensile, and<br />hemolytic properties. In nanocomposite films with 3 mass% of tannic acid/tin oxide<br />and coated with polyamide, an enhancement in tensile strength and elongation was<br />observed as compared to the neat p-PVC. It was found that by incorporating the<br />low content of nanofiller in poly(vinyl chloride) system, the migration of di(2-ethylhexyl)<br />phthalate effectively reduced and no significant changes in mechanical properties<br />of the poly(vinyl chloride) films were found. Furthermore, all samples did not<br />cause any hemolytic grade of the test material which suggested that the sample had<br />blood compatibility property.
