摘要：
In aqueous solutions of sodium polystyrene sulfonate (PSS) the different degree of neutralization is realized by electrostatic interaction with cationic surfactants ( cetyltrimethylammonium chloride ( CTAB) or didodecyldimethylamnionium bromide (DDAB)) added. The aggregation behavior of adducts of PSS and cationic surfactants with different degree of neutralization (DN) is studied by several methods in aqueous solution, such as the transmittance measurements, the fluorescence spectrum, fluorescence probe and the observation of scanning electron microscopy. The results indicate that PSS-CTAB (DDAB) nano-particles with a diameter of about 70 nm could be synthesized and possess hydrophilic shell and loose hydrophobic core into which the pyrene molecules can enter.
