摘　　要：通过超声波辅助液相法将纳米银(AgNPs)与氧化石墨烯(GO)结合制得了一种新的负载纳米银的氧化石墨烯材料AgNPs@GO。分析表明在该材料中AgNPs主要被锚接在GO片层的含氧基团和缺陷上,部分Ag单质被氧化为Ag^+离子并有部分GO被还原。AgNPs@GO能有效抑制铜绿假单胞菌生长,其抑菌能力显著强于AgNPs和GO。将AgNPs@GO作为添加剂引入聚乙烯(PE)基体,进一步制备了新型的AgNPs@GO掺杂PE复合材料0.48wt%-AgNPs@GO/PE,相比PE和AgNPs掺杂PE复合材料,0.48wt%-AgNPs@GO/PE具有更好的抑菌能力和更强的阻隔水蒸气性能,并且在水和乙醇溶液中都具有较好的耐溶出性能。A new nano silver particels loaded graphene oxide (AgNPs@GO) was obtained through ultrasonic assisted liquid phase method. In AgNPs@GO, nano silver particels (AgNPs) are mainly anchored at oxygen containing groups and defects of graphene oxide (GO) sheets, part of GO sheets are reduced and some Ag(0) atoms have been oxidized to Ag^+ ions. AgNPs@GO exhibits significantly stronger ability for inhibiting Pseudomonas aeruginosa than that of AgNPs and GO. Therefore, AgNPs@GO was further introduced to polyethylene (PE) matrix as an additive to prepare a new composite material 0.48wt%-AgNPs@GO/PE. Compare with bare PE and AgNPs doped PE composites, 0.48wt%-AgNPs@GO/PE not only has a better antibacterial ability and stronger water vapor barrier property, but also dissolves out less nonvolatile substance than PE in water and ethanol solution.
