以规则溶液理论研究了bola型阳离子两亲分子与十二烷基硫酸钠(SDS)混合体系的表面和胶团相互作用.相互作用参数的数值表明,bola分子与SDS在胶团中和溶液表面都发生了强烈的相互作用,这种相互作用的强度与普通季铵盐/烷基硫酸钠混合体系相当.这说明bola分子与SDS混合体系中的协同作用主要是由亲水基之间的静电相互作用产生的,而bola分子结构中疏水部分对相互作用没有显著影响.
The interaction between bola-type cationic amphiphiles and sodium dodecyl sulfate (SDS) system was investigated by the regular solution theory. The interaction parameters showed that the interaction of bola molecules with SDS in micelles and the solution surface Have a strong interaction, the strength of this interaction with the ordinary quaternary ammonium salt / sodium alkyl sulfate mixed system.This shows that the synergy between the bola molecules and SDS mixed system is mainly composed of electrostatic interaction between hydrophilic groups Interaction, whereas the hydrophobic part of the bola molecular structure has no significant effect on the interaction.
