A novel cellulose-based antibacterial material, namely silver nanoparticles@ metal-organic frameworks@ carboxymethylated fibers composites (Ag NPs@ HKUST-1@ CFs), was synthesized. The results showed that the metal-organic frameworks (HKUST-1) were uniformly anchored on the fiber's surfaces by virtue of complexation between copper ions in HKUST-1 and carboxyl groups on the carboxymethylated fibers (CFs). The silver nanoparticles (Ag NPs) were immobilized and well-dispersed into the pores and/or onto the surfaces of HKUST-1 via in situ microwave reduction, resulting in the formation of novel Ag NPs@ HKUST-1@ CFs composites. The antibacterial assays showed that the as-prepared composites exhibited a much higher antibacterial activity than Ag NPs@ CFs or HKUST-1@ CFs samples.
一种新型的基于纤维素的抗菌材料,即银纳米粒子@金属有机骨架@羧甲基化纤维复合材料(Ag NPs@HKUST-1@CFs)被合成。结果表明,金属有机骨架(HKUST-1)通过 HKUST-1 中的铜离子与羧甲基化纤维(CFs)上的羧基之间的络合作用均匀地锚定在纤维表面上。银纳米粒子(Ag NPs)通过原位微波还原被固定并良好地分散到 HKUST-1 的孔中和/或表面上,从而形成新型的 Ag NPs@HKUST-1@CFs 复合材料。抗菌试验表明,所制备的复合材料表现出比 Ag NPs@CFs 或 HKUST-1@CFs 样品更高的抗菌活性。
