采用熔融共混法制备了不同重量分数的PBS/纳米碳酸钙复合材料。研究了复合材料的热性能、动态力学性能和流变性能。DSC测试表明，纳米caco3颗粒对PBS的结晶和熔化行为影响不大。热重分析表明，纳米caco3的加入有利于提高PBS的热稳定性。动态力学分析表明，当纳米caco3含量不超过3wt%时，PBS/纳米caco3复合材料的G′和G”得到显著改善，而当纳米caco3含量超过3wt%时，G′和G”主要由PBS基体决定。流变学结果表明，G′
PBS/nano-CaCO3 composites with various nano-CaCO3 weight fractions were prepared by melt blending. The thermal behavior, dynamic mechanical properties and rheological properties of the composites were investigated. DSC measurements revealed that the nano-CaCO3 particles had little influence on the crystallization and melting behavior of PBS. Thermogravimetric analysis showed that the introduction of nano-CaCO3 tended to improve the thermal stability of PBS. Dynamic mechanical analysis showed that the G' and G '' of the PBS/nano-CaCO3 composites were improved significantly when the nano-CaCO3 content was not more than 3wt%, while the G' and G '' were mainly decided by the PBS matrix when the nano-CaCO3 content exceeded 3wt%. Rheological results showed that G'
