The adsorption is an entropy-driven process.
对季铵盐Gemini表面活性剂气液界面吸附的热力学参数进行研究,发现焓变(ΔH)和熵变(ΔS)呈线性关系,表明表面活性剂的气液界面吸附过程与其胶团化过程一样存在焓熵补偿现象,补偿温度为303 K左右,为熵驱动过程。
Making use of the hard sphere model in binary colloid, the mechanism of entropy-driven phase transitions was discussed, where the excluded volume plays an important role.
利用二元胶体的硬球模型,讨论了胶体的熵驱动相变机制,排斥体积发挥了重要作用,增加小球的自由体积,导致系统的平移熵增加,同时系统的混合熵减少,随着溶液浓度增加,必须保证小球有足够的平移熵,导致系统相分离的发生,溶液呈现宏观有序。
