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 didodecyldimethylammonium bromide(DDAB))added.The aggregation behavior of adducts of PSS and cationic suffactants 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 hydrophilie shell and loose hydrophobic core into which the pyrene molecules can enter.
