摘要: 通过自由基引发溶液聚合反应,合成星状C60-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 C60-styrene-acrylic acid copolymer [C60-poly(S-AA)] was synthesized successfully. The layer-by-layer self-assembly diazoresin/C60-poly(S-AA) films were fabricated. The crosslinking structure formed from the conversion of ionic bond to covalent bond after UVirradiation. The roughness and microtribological property of these C60-containing films were investigated by AFM/FFM, which shown the films are promising for lubrication materials.

Key words: Star-shaped C60-containing polyelectrolyte, Self-assembly film, Roughness, Microtribological property, AFM, FFM
