规则溶液理论应用于bola/SDS混合体系的研究
摘要:
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 Study of Bolaamphiphile/SDS Mixed Systems by Applying the Regular Solution Theory
Abstract:
The interaction of molecules on the surface and in the micelle of the mixed system of cationic bolaamphiphile/sodium dodecyl sulfate(SDS) was studied by using regular solution theory. The interaction parameter indicates that strong interaction exists both in the surface adsorption layer and in the micelle. The strength of the interaction is similar to that of conventional alkyl quaternary ammonium salt/alkyl sodium sulfate mixed system. This means the synergism in the bolaamphiphile/SDS mixed system is mainly caused by the electrostatic interaction between the hydrophilic head group, but not apparently affected by the hydrophobic part of the bola molecules.
