以阳离子聚合物JR-400和阴离子表面活性剂十二烷基苯磺酸钠（SDDBS）为主要成分，制备了有机可溶的聚电解质-表面活性剂复合物（PSC）。JR-400/SDDBS在乙醇中的比浓粘度出现反常现象，加入0.05N和0.1N KBr后，这种反常现象得到抑制。JR-400/SDDBS在乙醇中的光散射测量显示4个峰属于非聚集和聚集的多络合物颗粒。通过扫描电子显微镜（SEM）和原子力显微镜（AFM）对沉积在SiO2表面上的聚电解质-表面活性剂复合物薄层的元素组成和形貌进行了评价。使用AFM和表面增强椭圆偏振对比（SEEC）显微镜数据评估的PSC聚集体的高度具有良好的一致性，并且范围在10-50 nm内。XRD分析表明，PSC具有非晶态结构，在20 °附近有一个宽晕。接触角的测量被用来证明在沉积PSC后的玻璃表面的疏水化。
Organosoluble polyelectrolyte-surfactant complexes (PSCs) based on cationic polymer – JR-400 and anionic surfactant – sodium salt of dodecylbenzenesulfonate (SDDBS) were isolated as a precipitate from polyelectrolyte/surfactant aqueous mixture. The reduced viscosity of JR-400/SDDBS in ethanol showed polyelectrolyte anomaly that was suppressed upon addition of 0.05N and 0.1N KBr. Light scattering measurements of JR-400/SDDBS in ethanol showed 4 peaks belonging to non-aggregated and aggregated polycomplex particles. The elemental composition and morphology of thin layers of polyelectrolyte-surfactant complexes deposited on SiO2 surface were evaluated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The height of PSC aggregates evaluated using AFM and Surface Enhanced Ellipsometry Contrast (SEEC) microscopy data is in good agreement and range within 10–50 nm. The XRD analysis revealed that PSCs have amorphous structure with a broad halo near 20 °. The contact angle measurements were used to demonstrate the hydrophobization of glass surface after the deposition of PSCs.
