我们提出了一种嵌段共聚物，聚（二羟基苯乙烯-嵌段-苯乙烯）（PDHSt-b-PSt），它含有邻苯二酚基团的侧链的PDHSt部分。由于邻苯二酚基团能自动还原银离子至金属态，因此，以嵌段共聚物为还原剂，在室温下合成了嵌段共聚物稳定的有机溶剂分散的银纳米粒子（NPs）。通过改变嵌段共聚物PDHSt的分子量来控制Ag NP的尺寸。
We proposed a block copolymer, poly(dihydroxystyrene-block-styrene) (PDHSt-b-PSt), that contains catechol groups in the side chains of PDHSt moieties. Since catechol groups automatically reduce silver (Ag) ions to theirmetallic state, the block copolymer was used as a reductant to synthesize organic-solvent-dispersive Ag NPs (NPs) stabilized with the block copolymer at room temperature. Ag NP sizes were controlled by changing molecular weights of PDHSt of the block copolymer.
