| 中文摘要: |
| 二硫化钼( MoS2)是一类常用的无机耐磨填料，将其填充到聚合物基复合材料中之前，为提高其与聚合物之间的界面相容性，并防止发生团聚而影响分散性，需要对其进行表面改性。采用马来酸酐( MA)为改性剂，对MoS2粉体进行表面改性研究。改性后的MoS2粉体在非极性溶剂中的分散性提高，其悬浮液离心分离后，上层清液的浊度从215提高到234，活化指数从0.42提高到0.8，吸油量从0.68mL/g降为0.31mL/g，透水时间明显延长，表明改性后的MoS2粉体亲油性提高。探讨了改性机理，并采用FT-IR及XRD进行了结构表征，结果表明：MA水解产物中的羧基与MoS2表面的羟基生成氢键，并定向包覆在MoS2微粒表面上，而酯基具有亲油疏水性。 |
| 英文摘要: |
| MoS2 is a common inorganic wearable filler. In order to improve the surface consistence between the MoS2 and the polymeric compound, also, to prohibit the agglomeration of MoS2 powder, the power is often modified through some organic reagents. MoS2 powder were modified by MA. The modified powders dispersity increased in nonpolar solvent, its suspending liquids turbidity increased from 215 t0 234 NTU, activation data became t0 0.8, 011 absorption reduced t0 0. 31 mL/g, and the penetration time obviously extended. The result shown that the lipophilicity of modified MoS2 increased. Also, by the synthesis with FT-IR, XRD and investigation of modification principle, it was found that the MoS2 particles'surface were covered by MA. |
