나노 버블 이용한 폴리옥시에틸렌 알킬 에테르에 의한 기/액 계면에서 표면전하에 관한 연구 |
| 초록 |
A simple and convenient method to measure micro-electrophoretic mobilities was proposed to determine the zeta-potential of nanobubbles generated by ultrasonication. Bubbles in aqueous solutions of polyoxyethylene alkyl ether with different alkyl chain lengths and EO numbers were sonicated with a palladium-coated electrode designed specially by the manufacture. The zeta-potentials of bubbles in surfactant solutions at all PH values are negative. As the chain length of polyoxyethylene alkyl ether increases, zeta-potentials decrease at high PH. This study has shown that the chemical properties of functional group in the head group of non-ionic surfactants are also an important factor for charging as well as the polarity of non-ionic surfactants consisting of bubble interface |
