摘　　要：采用共混改性的方法制备了聚丁二酸丁二醇酯/海泡石复合材料,通过能谱分析法和旋转流变仪研究了不同海泡石含量在聚丁二酸丁二醇酯(PBS)中的分散情况及其对PBS流变性能的影响。随着海泡石含量的增加,海泡石在PBS基体中越来越密集,但分散仍然均匀。当海泡石含量为10wt%时,复数黏度与储能模量提高了3倍左右。随后,我们利用超临界CO_(2)发泡技术对PBS/海泡石复合材料进行发泡,进一步探究海泡石(Sep)对泡孔结构及吸水、吸油量的影响。实验结果表明,在10wt%的PBS/海泡石开孔泡沫中,泡孔分布均匀,且吸水、吸油性能最佳。Polybutylene succinate/sepiolite composites were prepared by blending modification,and the dispersion of different sepiolite contents in polybutylene succinate(PBS)and its influence on PBS rheological properties were studied by energy spectroscopy and rotational rheometer.As the content of sepiolite increased,sepiolite became denser in PBS matrix,but the dispersion was still uniform.When the sepiolite content was 10wt%,the complex viscosity and storage modulus increased by about 3 times.Subsequently,supercritical CO_(2) foaming technology was used to foam PBS/sepiolite composites to further explore the effects of sepiolite on cell structure,water absorption and oil absorption.The experimental results showed that in 10wt%PBS/sepiolite open-cell foam,the cell distribution was uniform,and the water absorption and oil absorption performance were the best.
