| 摘 要： | 利用原子力显微镜(AFM)中的敲击模式原子力显微镜(TM-AFM)和摩擦力显微镜(FFM)对不同含量聚己内酯-b-聚二甲基硅氧烷-b-聚己内酯三嵌段(PCL-b-PDMS-b-PCL)共聚物复合环氧树脂的表面富集结构进行了分析研究. TM-AFM测试在不同作用力下得到了PCL-b-PDMS-b-PC 含量不同环氧树脂表面及其亚表面的分相结构; 同时利用FFM对其表面进行摩擦和磨损试验. 结果表明, PCL-b-PDMS-b-PCL含量不同时摩擦性能表现出较大的变化, 当其质量分数达到30%时, 表面性能达到了稳定. 接触角试验也验证了以上的结果.

| Abstract: | The surface enrichment and phase separation structures of epoxy resin and poly(ε-caprolactone)-block-polydimethylsiloxane-block-poly(ε-caprolactone) triblock copolymer (PCL-b-PDMS-b-PCL) blends were studied using tapping mode atomic force microscopy (TM-AFM) and frictional force microscopy (FFM). Friction and wear properties show that the surface is enriched with the PDMS component and it reaches a stable state at a PCL-b-PDMS-b-PCL mass fraction of about 30%. Contact angle measurements on the surface also support these results. |
