| Research Abstract |
The objective of this research is to specify the materials which can generate spontaneous interface tension change. We focus on the famous Dupeyrat's system, i. e., saturated KI/I_2 nitrobenzene solution and stearylammonium chloride(STA-Cl) aqueous solution. Thanks for this budget, we could obtain two important results as described below(1) The mechanism of the activation of the spontaneous motion of a nitrobenzene droplet by chlorobenzene blending was revealed.(2) Spontaneous interface tension change system without I_2(Saturated NaCl nitrobenzene/STA-Cl aqueous solution, and saturated ZnCl_2 nitrobenzene/STA-Cl aqueous solution) was discovered and the mechanism was proposed.
