Poly(vinylidene fluoride) (PVDF) polymers are utilized in the processing of foods and beverages due to their highly stable nature. This makes plasticizer selection crucial. The incorporation of epoxidized oleic acid (EOA) as a bio-plasticizer into PVDF in the solution blending process was investigated. Scanning electron microscopy analysis showed the toughening effects in the structure of the blends. The degree of crystallinity was found to decrease with an increase in the EOA ratio. The melting temperature slightly decreased with the addition of EOA. A reduction was observed in the glass transition temperature (T _g), which was the effect of the plasticizer. Bio-plasticized PVDF exhibited increased thermal resistance with higher char formation. The scanning electron fractograph showed that EOA disrupted the PVDF crystallinity with a rise in amorphicity. Crystal formation was found to be in one dimension and dependent on the bio-plasticizer content. Hence, EOA has an excellent potential as a renewable resource to substitute for conventional petroleum-based plasticizers.

将环氧化油酸增塑剂掺入聚偏二氟乙烯中

聚偏二氟乙烯 (PVDF) 聚合物由于其高度稳定的性质而被用于食品和饮料的加工。这使得增塑剂的选择至关重要。研究了在溶液共混过程中将环氧化油酸（EOA）作为生物增塑剂掺入 PVDF 中。扫描电子显微镜分析显示了共混物结构的增韧作用。发现结晶度随着EOA比率的增加而降低。随着EOA的添加，熔化温度略有降低。观察到玻璃化转变温度 ( T _g），这是增塑剂的作用。生物增塑 PVDF 表现出更高的热阻和更高的炭形成量。扫描电子断裂图显示 EOA 破坏了 PVDF 的结晶度，导致无定形度增加。发现晶体的形成是一维的并且取决于生物增塑剂的含量。因此，EOA作为可再生资源具有替代传统石油基增塑剂的巨大潜力。
