In the present study, a renewable resource‐based plasticizer was synthesized by the lipase‐catalyzed esterification reaction of furfuryl alcohol (FA) and castor oil fatty acid (COFA). The resultant ester (FA‐COFA ester) was used as secondary plasticizers to the polyvinyl chloride (PVC) films. The PVC films were formulated using the combination of a conventional plasticizer di‐butyl phthalate (DBP) and FA‐COFA ester as a secondary plasticizer at different concentrations. Films were characterized by X‐ray diffraction analysis, scanning electron microscopy, thermal analysis, mechanical performance, and migration stability. A biodegradability study of the PVC films showed increased degradability with increasing concentration of the FA‐COFA ester in the PVC film. The study showed that ester of FA and COFA could be a substitute of DBP by as much as 80% of the total plasticizer with improved elongation and tensile properties, and such a kind of sustainable resource‐based PVC blend films could be used as a good packaging material with biodegradable property.

蓖麻油基增塑剂对聚氯乙烯薄膜的性能评价和生物降解研究

在本研究中，通过糠醇（FA）和蓖麻油脂肪酸（COFA）的脂肪酶催化酯化反应合成了可再生资源基增塑剂。所得的酯（FA-COFA酯）用作聚氯乙烯（PVC）薄膜的辅助增塑剂。PVC膜是使用常规增塑剂邻苯二甲酸二丁酯（DBP）和FA-COFA酯作为辅助增塑剂以不同浓度配制而成的。通过X射线衍射分析，扫描电子显微镜，热分析，机械性能和迁移稳定性来表征薄膜。PVC膜的生物降解性研究表明，随着PVC膜中FA-COFA酯浓度的增加，降解性也随之提高。
