| 摘 要： | 本文提出一种制备具有高金属覆载率及良好均匀性的PS/Ag复合微球的简便方法,可以避免PS微球的表面修饰。首先通过多元醇法制备具有良好单分散性的PVP覆盖的Ag纳米颗粒, 然后通过溶胀-异质凝聚法将这些Ag纳米颗粒负载于PS球上。对Ag纳米颗粒的尺寸分布及PS/Ag复合微球的表面形貌进行了研究,结果表明这种方法制得的PS/Ag复合微球具有良好的分散性与均一性,并且Ag颗粒的负载率可以通过Ag溶胶的加入量来调控。

| Abstract: | A facile method to synthesis PS/Ag composite microspheres with high and uniform metal coverage was proposed in this article, therefore avoiding the modification of PS beads. First, polyvinylpyrrolidone (PVP)-capped Ag NPs with a narrow size distribution were obtained by the modified polyol process, and then the PVP-capped Ag NPs were successfully loaded on the PS beads by using a combined swelling-heteroaggregation (CSH) procedure. The size distribution of Ag NPs and the morphology of PS/Ag composite microspheres were investigated. The results show that well-dispersed and uniformly coated PS/Ag microspheres are obtained and the coverage of the Ag NPs can be controlled by changing the amount of Ag NPs. |
