Abstract
Spontaneous motion of nitrobenzene droplet including only iodine (potassium iodide-free) in cation surfactant aqueous solution was investigated. For quantitative clarification of the motion mechanism, the contact angle of droplet and the concentrations of iodic components in this system, i.e. I2, I−, IO3−, and I3−, were measured. A disproportionate reaction of iodine in the alkaline conditions to produce iodide and iodate ions was identified, inducing the reduction of the droplet contact angle. A significant relation between running distance of spontaneous droplet motion and the droplet contact angle was found. The mechanism of motion was discussed based on these results.
