摘 要:利用桐酸铁作为光敏剂,与聚丙烯树脂共混制备了可光降解的聚丙烯复合材料。并将桐酸铁对聚丙烯树脂的光降解效果与硬脂酸铁、油酸铁对聚丙烯树脂的光降解效果进行对比。通过光学显微镜、DSC、TG等多种方法表征证明桐酸铁对聚丙烯树脂的光降解效果要优于硬脂酸铁和油酸铁。

Abstract:Photodegradable polypropylene composite was prepared using the eleostearic acid iron salt as photosensitizer and mixed with polypropylene resin. The photodegradation effect of eleostearic acid iron salt on polypropylene resin was compared with that of iron stearate and iron oleate on polypropylene resin.Optical microscope, DSC and TG were used to demonstrate that the photodegradation effect of eleostearic acid iron salt on polypropylene resin was better than that of iron stearate and iron oleate.
Key words:polypropylene; eleostearic acid iron salt; photosensitizer; photodegradation
