Studies of Mocrotribological Property on the Self-assembly Films from Diazoresin and C60-containing Polyelectrolyte
【摘要】 通过自由基引发溶液聚合反应 ,合成星状 C6 0 -苯乙烯 -丙烯酸聚合物 ,其钠盐作为高聚物负离子 ,与高聚物正离子的重氮树脂在云母上自组装成膜 ,利用紫外光照射反应 ,使膜层间连接的离子键转化成共价键 .用原子力显微镜 (AFM)和摩擦力显微镜 (FFM)研究了不同链长和不同层数自组装膜的表面形貌及微摩擦性能
【Abstract】 The star shaped C 60 styrene acrylic acid copolymer [C 60 poly(S AA)] was synthesized successfully. The layer by layer self assembly diazoresin/C 60 poly(S AA) films were fabricated. The crosslinking structure formed from the conversion of ionic bond to covalent bond after UV irradiation. The roughness and microtribological property of these C 60 containing films were investigated by AFM/FFM, which shown the films are promising for lubrication materials.
