用分子沉积技术制备了聚丙烯胺(PAH)/石墨氧化物(GO)多层分子沉积薄膜, 为了增大薄膜自身的结合强度, 采用加热的方式使其成膜动力发生转变. 用紫外光谱及原子力显微镜(AFM)考察了薄膜的微观结构及其纳米摩擦学性能. 结果表明, 薄膜能够有效降低玻璃表面的摩擦, 加热后薄膜成膜动力由静电结合转变为价键结合的形式, 同时摩擦力的变化取决于薄膜表面硬度和形貌. Polyamidoamine (PAH) / graphite oxide (GO) multi-layer molecular deposition films were prepared by molecular deposition technique. In order to increase the bonding strength of the film itself, the kinetics of film formation were changed by heating. Atomic Force Microscope (AFM) investigated the microstructure and the tribological properties of the films. The results show that the film can effectively reduce the friction of the glass surface, and the filming power of the film changes from electrostatic to valence bond when heated. Meanwhile, The change depends on the film surface hardness and morphology.
