In this study, we prepared a green heat stabilizer tannic acid–calcium oxide (TA–CaO) adduct in a green method and its efficacy was studied in a bio-based polyvinyl chloride-thermoplastic starch polymer matrix. The composite was prepared in a green pathway by melt mixing. CaO in the prepared complex also acted as a reinforcing filler in the composite. The addition of TA–CaO adduct in place of lead carbonate improved all the physical and chemical properties of the composite. The tensile strength and flexural strength improved to 102% and 127%, respectively, in comparison with similar percentage of lead carbonate and TA–CaO adduct. The composite with 15 phr loading of TA–CaO showed improved properties compared with other TA–CaO loaded composites.

单宁酸-氧化钙加合物作为绿色热稳定剂和增强填料在生物基杂化聚氯乙烯-热塑性淀粉聚合物复合材料中的作用研究

在这项研究中，我们以绿色方法制备了一种绿色热稳定剂单宁酸-氧化钙 (TA-CaO) 加合物，并在生物基聚氯乙烯-热塑性淀粉聚合物基质中研究了其功效。通过熔融混合以绿色途径制备复合材料。制备的复合物中的 CaO 也作为复合物中的增强填料。添加 TA-CaO 加合物代替碳酸铅改善了复合材料的所有物理和化学性能。与类似百分比的碳酸铅和 TA-CaO 加合物相比，拉伸强度和弯曲强度分别提高到 102% 和 127%。与其他负载 TA-CaO 的复合材料相比，负载 15 份 TA-CaO 的复合材料显示出更好的性能。
