摘要：
Ag nanoparticles were firstly encapsulated into graphene oxide (GO) scrolls to form GO-Ag scrolls by a molecular combing method. Horizontally and perpendicularly aligned GO-Ag scrolls were then crossly stacked by a dry transfer method to form GO-Ag scroll meshes. After being reduced by hydrazine, the device based on reduced GO-Ag (rGO-Ag) scroll meshes shows 3 orders of magnitude higher response in humidity sensing compared to that of reduced GO (rGO) scroll meshes. In addition, rGO-Ag scroll meshes-based device shows good humidity sensing stability in ambient conditions over a month.
