摘　　要：采用2种表面处理剂对纳米CaCO3进行表面处理,通过电镜、电子能谱仪、接触角测试仪、红外分光光度计等观察分析了处理前后的纳米CaCO3的微观结构及性能的变化。结果表明,表面处理剂B有效地促进了纳米CaCO3粒子的分散和细化;2种表面处理剂均使纳米粒子的表面能降低,并改善其表面亲油性。The surface of nano-CaCO 3 was treated by two surface treatment agents. The microstructure and the change of properties were analyzed. The results showed nano-CaCO 3 particles were dispersed and fined in effect by surface treatment agent B, surface energy of nano-CaCO 3 particles was reduced, hydrophobic property was improved by two surface treatment agents.
