| 摘 要： | 使用搅拌磨湿法机械力化学方法对绢云母质二维纳米薄片材料进行了表面改性.采用钛酸酯偶联剂作为表面改性剂研究了改性剂用量、介质物料比、磨矿浓度、改性时间以及温度和pH值对改性效果的影响,并对最终改性产品填充聚丙烯(PP)后的复合材料进行了性能测试.结果表明,采用机械力化学方法对二维纳米材料进行改性是可行的,填充改性产品PP复合材料具有较强的抗紫外线性能. |

| Abstract: | The mechanochemical surface modification of two-dimension sericite flaky nano-materials was investigated through the grinding of a stirred mill. With titanite as the surface modification agent of sericite, the effects of the dosage of modification agent, massic ratio of midium/sericite, density of slurry, grinding time, temperature and pH value on the surface modification were analyzed. The properties of polypropylene (PP) filled with the modified filler were tested. The result shows that it is feasible to modificate two-dimension sericite flaky nano-materials mechnochemically and the composite materials of PP filled with the modified filler have a better capacity of resisting ultraviolet radiation. |
