摘要：将聚酰胺-胺(PAMAM)树形大分子、聚对苯乙烯磺酸钠(PSS)和聚二烯丙基二甲基氯化铵(PDADMAC)在三聚氰胺甲醛(MF)微球上进行静电自组装,制得聚电解质壳层的核壳式微球.通过反应沉积吸附方法生成具有稳定荧光性能的CdS/聚电解质核壳式复合微球.用透射电镜表征复合微球形貌,用反射紫外和荧光表征了CdS/聚电解质核壳式复合微球的光学特性.
Core-shell microspheres with polyelectroly-te multilayers were fabricated by electrostatic self-assembly of three kinds of polyelectrolyte, such as polyamidoamine （PAMAM）, poly（diallyldimethylammonium chloride） （PDADMAC） and poly（4-styrenesulfonate） （PSS）. Core-shell microspheres with CdS/polyelectrolyte multilayers were prepared by deposition and＂ adsorption of CdS on the polyelectrolyte multilayers, and the CdS nanoparticles were formed in solution or polyelectrolyte layer, the formed core-shell microspheres had stable photoluminescence property. TEM was used to characterize the shape of core-shell microspheres and photonic properties of core-shell microspheres with CdS/polyelectrolyte multilayers were analyzed by UV-Vis reflectance and photoluminescence spectra.
