采用偏光显微镜、差示扫描量热法和广角X射线衍射法研究了α-环糊精（α-CD）对聚3-羟基丁酸酯（PHB）结晶行为的影响。我们发现α-CD的加入可以极大地促进PHB的结晶，并且α-CD不仅具有促进成核的潜力，而且还具有促进PHB结晶的潜力。与传统的成核剂如滑石相比，α-CD是一种天然产物，具有许多优点，因为它对环境友好且对人类安全。(C)2004 Wiley Periodicals，Inc.
The effect of alpha-cyclodextrin (alpha-CD) on the crystallization behavior of poly(3-hydroxybutyrate) (PHB) was investigated with polarized optical microscopy, differential scanning calorimetry, and wide-angle X-ray diffraction. We found that the addition of alpha-CD can greatly accelerate the crystallization of PHB and that alpha-CD has a potential not only to enhance the nucleation but also to accelerate the crystallization of PHB. Compared to a conventional nucleation agent, such as talc, alpha-CD is a natural product and has many advantages because it is environmentally friendly and safe to humans.
