Ordered honeycomb-structured gold nanoparticle films with changeable pore morphology: from circle to ellipse.
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.
