| 摘 要： | 目的 探索静电力对自组装膜表面上二维胶体粒子晶格结构的影响。方法 在硅和玻璃基底表面，采用自组装方法和表面反应得到带不同基团的自组装膜基底，通过控制基底自组装膜表面的电荷性质形成二维胶体粒子晶格结构。结果 当表面和胶体粒子带有相同的电荷基团时，静电斥力增加了粒子在表面的运动性，可以形成大面积的二维胶体粒子晶格结构；当表面和胶体粒子带有相反的电荷基团时，静电吸引作用阻碍了粒子在表面的运动，胶体粒子更容易吸附在自组装膜表面而形成无规则的单层胶体粒子结构。结论 提供了一种制备高质量大面积的二维胶体粒子品格结构的新方法。

| Abstract: | Objective To investigate the influence of electrostatic forces on two-dimensional crystals of colloidal particles on self-assembled monolayers.Methods Various groups terminated self-assembled monolayer were formed on glass and silica surface. The two-dimensional crystals of colloidal particles on these surfaces were studied. Results High orderly two-dimensional crystals of colloidal particles were formed when colloidal particles and SAMs surface have the same charges. Conclusion The electrostatic and electrostatic repulse forces caused the main effect on the structure of two-dimensional crystals. A new way was found to fabricate high-orderly two dimensional crystals of colloidal particles. |
