    摘要:

    本文提出一種制備具有高金屬覆載率及良好均勻性的PS/Ag復(fù)合微球的簡(jiǎn)便方法,可以避免PS微球的表面修飾。首先通過(guò)多元醇法制備具有良好單分散性的PVP覆蓋的Ag納米顆粒, 然后通過(guò)溶脹-異質(zhì)凝聚法將這些Ag納米顆粒負(fù)載于PS球上。對(duì)Ag納米顆粒的尺寸分布及PS/Ag復(fù)合微球的表面形貌進(jìn)行了研究,結(jié)果表明這種方法制得的PS/Ag復(fù)合微球具有良好的分散性與均一性,并且Ag顆粒的負(fù)載率可以通過(guò)Ag溶膠的加入量來(lái)調(diào)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.
