摘要(Abstract)：

为扩大甜菜碱类两性离子表面活性剂的应用范围，利用气泡振荡方法，研究了溶液pH值对支链化羧基甜菜碱（C16GPB）表面吸附膜性质的影响。结果表明：C16GPB分子在酸性条件下呈现阳离子特性，在强碱性条件下表现部分阴离子特性；适宜的酸性环境（pH=5）和强碱性环境（pH=13）中，C16GPB亲水基团在表面的取向从垂直向平铺变化，同时，表面活性剂吸附分子间存在静电斥力，成膜时间长达20 000 s左右；当C16GPB溶液呈酸性或强碱性时，分子间相互作用以静电斥力为主，扩散-交换快弛豫过程控制表面膜性质，表面膜的弹性模量降低；中性和弱碱性条件下，表面重排慢弛豫过程起主导作用，表面扩张弹性模量高达100 m N/m以上，膜强度较大，易于形成稳定的泡沫。
