使用具有不同烷基链长度的表面活性剂改变离子强度，对阳离子表面活性剂吸收到阴离子聚合物网络中的动力学进行了研究。表面活性剂的吸收速率强烈依赖于表面活性剂的烷基尺寸和离子强度，并解释了两个因素：表面活性剂的扩散过程和结合过程。建立了表面活性剂扩散的数学模型，通过数值求解扩散方程，考虑了表面活性剂的结合过程。所得结果与实验结果进行了比较。
Kinetic studies of the cationic surfactant uptake into an anionic polymer network have been made using surfactants with various alkyl chain lengths changing ionic strength. The rate of the surfactant uptake is strongly dependent on the surfactant alkyl size and ionic strength, and it was explained in terms of two factors: surfactant diffusion process and binding process. A mathematical model for the surfactant diffusion was developed, taking into account the surfactant binding process by numerically solving diffusion equations. The obtained results were compared with those of experiments.
