通过DSC和偏光光学显微镜（POM）研究了甲基化CD、α-和β-DMCD以及α-和β-TMCD对P(3HB)结晶行为的影响。通过添加适量的每种甲基化CD可以改善P(3HB)的结晶和成核，但是当添加量超过最大成核效果的最佳值时，观察到可混溶共混物的负面影响。 β-TMCD 被证明对于增强 P(3HB) 结晶最有效，这被认为是由于与 P(3HB) 形成 IC 的可能性。
The effects of methylated CDs, a- and β-DMCD and a- and β-TMCD on the crystallization behavior of P(3HB) have been investigated by employing DSC and polarized optical microscopy (POM). The crystallization and nucleation of P(3HB) was improved by an addition of appropriate amount of each methylated CD, while negative effect of miscible blend was observed when the amount of addition exceeds the optimum value for the maximum nucleating effect. β-TMCD was shown to be the most effective for the enhancement of the P(3HB) crystallization, thought to be due to the possibility of IC formation with P(3HB).
