表面处理对TiO_2/PP复合材料界面的影响

Influence of Surface Treatment on Interface of TiO_2/PP Composite

采用硅烷偶联剂对TiO2 颗粒进行表面处理改性并与聚丙烯 (PP)共混填充。通过红外光谱分析和扫描电镜分析研究了表面处理对TiO2 /PP界面结合的改性效果 ,研究了表面处理对TiO2 /PP复合材料的流动性能的影响。研究结果表明 ,表面处理可以明显改善复合材料的流动性能。

The surface of TiO 2 particles was treated by siliane coupling agent firstly,and then blended with PP.The influence of surface treatment on the interface of the PP/TiO 2 composite was studied by IR spectrum and SEM.Also was the influence of surface treatment on the flowing property.The results show that the flowing property and combination of the interface can be improved obviously by surface treatment.
