采用差示扫描量热法和偏光显微镜观察研究了聚乙烯醇(PVA)微粒作为成核剂对细菌聚3-羟基丁酸酯(PHB)结晶行为的影响。并与PVA与PHB常规共混的效果进行了比较。结果表明，PVA微粒对PHB的结晶有显著的促进作用，而常规共混的PVA对PHB的结晶有极大的抑制作用。PVA微粉的成核作用与滑石粉相当。考虑到PVA的生物降解性和生物相容性，使用PVA粒子作为成核剂比目前使用的不可生物降解的成核剂如滑石粉和氮化硼具有显著的优势。©2006威利期刊公司J Polym Sci第B部分：Polym Phys 44：1813-1820,2006
The effect of poly(vinyl alcohol)(PVA) fine particles as the nucleating agent on the crystallization behavior of bacterial poly(3-hydroxybutyrate)(PHB) was studied using differential scanning calorimetry measurements and polarized light microscope observation. The results were compared with the effect of PVA conventionally blended with PHB. The PVA fine particles were found to be able to greatly enhance the crystallization of PHB, while the conventionally blended PVA extremely retarded the crystallization of PHB. The nucleating effect of PVA fine particles is almost comparable to that of the talc powder. Considering the biodegradability and biocompatibility of PVA, the usage of PVA particle as a nucleating agent provides marked benefits over the currently employed nonbiodegradable nucleating agents, such as talc and boron nitride. © 2006 Wiley Periodicals, Inc.
