Study on the role of tannic acid–calcium oxide adduct as a green heat stabilizer as well as reinforcing filler in the bio‐based hybrid polyvinyl chloride–thermoplastic starch polymer composite

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...
