摘　　要：以可生物降解的聚己二酸/对苯二甲酸丁二醇酯(PBAT)为基体,使用硅烷偶联剂对超细活性碳酸钙(CaCO_(3))进行改性,并将改性CaCO_(3)作为填料制备出可生物降解的PBAT/CaCO_(3)复合材料,对复合材料的流变性能和热性能进行了研究。低组分CaCO_(3)的PBAT/CaCO_(3)复合材料粘度降低、弹性增加,材料粘弹区间变宽,增加了使用范围,材料的热稳定性提高。Biodegradable Poly(butyleneadipate-co-terephthalate)(PBAT) composites were prepared by modifying ultrafine active calcium carbonate(CaCO_(3)) with silane coupling agent and using modified CaCO_(3)as filler. The rheological properties and thermal properties of the composites were studied. The viscosity of PBAT/CaCO_(3)composite with low CaCO_(3)component decreases, and its elasticity increases, the viscoelastic range of the material becomes wider, and the thermal stability of the material is improved.
