【摘要】 通过透光度测定、电导滴定和粘度法考察了阳离子聚电解质聚苯乙烯 4 乙烯基吡啶硫酸甲酯盐与阴离子表面活性剂十二烷基硫酸钠 (SDS)的相互作用。研究表明 ,在表面活性剂未过量时 ,二者之间的静电作用占主导地位 ,并且当二者电荷总量相等时 ,生成的复合物沉淀最多 ;在表面活性剂过量后 ,复合物可部分溶解 ,溶解的原因是疏水相互作用。本文初步阐述了二者的作用机理更多还原

【Abstract】 The interaction between polycation derived from poly(4-vinyl pyridine-styrene)and sodium dodecyl sulfate(SDS)was studied by transmittance determination, conductance titration and viscosity method.The results of the study indicated that the electrostatic function played a leading role when SDS is insufficient,and the most precipitate of polyelectrolyte-surfactant complex will be formed when their quantity of charge is equal.If SDS is used in excess,the precipitate will be partly dissolved because of hydrophobic interaction. The function mechanism was also explained.更多还原
