The interaction of anionic polymer polyacrylamide and cationic Gemini surfactants, namely: α,ω-bis(hexadecyldimethylammonium)alkane dibromides, (16-s-16), s = 5, 6 and their conventional counterpart cetyltrimethylammonium bromide (CTAB) has been investigated by electrical conductivity, rheology, and scanning electron microscopy (SEM) techniques. Stronger interaction of Gemini surfactants in comparison to their conventional counterpart CTAB was observed from conductivity studies, while viscosity studies show that the interaction is quite significant with Gemini surfactants. The thermodynamic parameters for interactions show feasibility of interaction between the polymer and surfactant. SEM results support the viscosity data.

阴离子聚丙烯酰胺与阳离子双子/常规表面活性剂之间的相互作用

阴离子聚合物聚丙烯酰胺和阳离子 Gemini 表面活性剂的相互作用，即：α,ω-双（十六烷基二甲基铵）烷烃二溴化物，(16- s -16), s  = 5, 6 及其常规对应物十六烷基三甲基溴化铵 (CTAB)电导率、流变学和扫描电子显微镜 (SEM) 技术。从电导率研究中观察到与传统对应物 CTAB 相比，Gemini 表面活性剂的相互作用更强，而粘度研究表明，与 Gemini 表面活性剂的相互作用非常显着。相互作用的热力学参数表明聚合物和表面活性剂相互作用的可行性。SEM 结果支持粘度数据。
