• 中文摘要： 本文有系統地探討SDDS-DDTMAC雙成分界面活性劑混合物的增效作用對降低表面張力和形成微胞的影響。結果顯示此一混合系統的增效作用非常顯著,而衡量界面活性劑分子在氣/液界面單分子層和微胞中交互作用程度的兩個參數則具有極大的負值。本文也使用電導度法決定正、負有機離子形成離子對複合體的化學量論及反應平衡常數,並以之驗證上述增效作用。
• 英文摘要： The synergistic effect on surface tension reduction and micelle formation was systematically studied for the binary mixtures of sodium dodecylsulfate (SDDS) and dodecyl trimethyl ammonium chloride ( DDTMAC). Significant synergism of this system results in large negative values of parameters .beta./sup .delta./ and .beta./sup m/, that measure the extent of the interaction between the two surfactants for mixed monolayer formation at aqueous solution/air interface and mixed micelle formation, respectively. The stoichiometry and equilibrium constant of the ion-pair complex formation between oppositely charged organic ions were also determined by means of the conductimetric method. Synergism affects through the formation of the equimolecular complex can then be verified.
