The surface and micelle property of C_7F_(15)COONa/C_3F_7CH_2OH aqueous solution are investigated by surface tension, conductance, electromotive force methods. The results show that when adding C_3F_7CH_2OH into C_7F_(15)COONa solution the surface activity of C_7F_(15)COONa and the counterion binding degree of micelle can be enhanced.

Key words: Fluorocarbon alcohol, Counterion binding degree, Surface activity
