| 摘 要： | 纳米碳酸钙(CaCO3)与聚苯硫醚(PPS)通过熔融共混挤出制得复合材料,通过透射电镜对纳米碳酸钙的形态及粒径分布进行观察,并用原子力显微镜、力学测试等方法对复合材料微观结构和力学性能进行表征.结果表明,纳米碳酸钙的平均粒径约56nm,从复合材料表面形貌可见纳米碳酸钙分散在树脂基体里,少量粒子变形;复合材料的韧性得到明显提高,在添加量为5wt%时,冲击强度达到74.13kJ/m2,抗拉强度则在10wt%时达到最大,83.73MPa. |

| Abstract: | Composites of polyphenylene sulfide reinforced with calcium carbonate nanopowder were prepared by compression molding.The distribution and morphology of fillers were characterized by transmission electron microscopy(TEM).By using atomic force microscopy(AFM),the detailed microstructure and fracture surface of the composite could be observed.The result showed that the average particle size of the CaCO_3 nanoparticles was about 56nm,tensile tests showed that the tensile strength was 83.73MPa when the addition was 10wt%,impact stress was 74.13kJ/m~2 when the addition was 5wt%. |
| Keywords: | nano-CaCO_3 PPS microstructure mechanical property AFM |
