Recently, poly(lactic acid) (PLA) is known as a biodegradable polymer that is being studied as a material of high industrial value. Biodegradable PLA could improve many environmental problems caused by using conventional plastics. Therefore, many studies are being conducted on PLA to control its crystallinity which is one of the main controlling parameters of properties. By controlling the crystallinity of PLA, it will be possible to use it in a wide range of industries. The previous studies on polyphenols have shown various advantages in antioxidant effects and biocompatibility. There are many types of polyphenols in fruits and vegetables of nature. In this study, we tried to make uniform PLA films and control the crystallinity of it. Polyphenols were used as a nucleant to control the crystallinity of PLA films. It is expected that a polyphenol could serve as a crystallization seed in making PLA films. This strategy could find a novel way to control the crystallinity of PLA. |
