Two-dimensionally ordered honeycomb structures have been prepared on dodecanethiol-capped gold nanoparticle films by blowing moist air across the surface of the nanoparticle solution. The pore morphology can be altered from circle to ellipse with tunable aspect ratios by carefully controlling the direction and velocity of airflow. The formation mechanisms of different surface morphologies have been discussed in terms of the surface and interfacial tension.
通过在十二烷硫醇包覆的金纳米颗粒溶液表面吹拂潮湿空气，在该溶液表面制备了二维有序蜂窝状结构。通过仔细控制气流的方向和速度，孔隙形态可以从圆形改变为具有可调纵横比的椭圆形。已根据表面张力和界面张力讨论了不同表面形态的形成机制。
