Abstract
Various forms of life need oxygen, and the unmanned diving machine also needs oxygen. However, it is limited under water in the present situation because of a capacity of oxygen cylinders. In nature, there are some special insects, which utilize superhydrophobic hair structures as physical gills, semipermanently living in water. We focused on this physical gill of the plastron and prepared artificial plastrons by using self-organized honeycomb-patterned films. In this paper, we showed the preparation of artificial plastrons and measurements of oxygen permeability in water. As results, durable honeycomb-patterned films resisting water pressure were obtained, and oxygen was transferred from water to inside of the bottles though the films. This phenomenon suggested the honeycomb-patterned films showed possibility of use as artificial plastrons.
