▎ 摘　　要

NOVELTY - Nano reactor comprises interface between a water layer of a lamellar phase and an organic layer of the lamellar phase, the nanoreactor forming Janus graphene oxide (GO) nanosheets from GO nanosheets and functional agents. USE - Nano reactor. ADVANTAGE - Janus material including forming a lamellar phase having water layers and organic layers, incorporating nanosheets and a functional agent into the lamellar phase, and attaching the functional agent to the nanosheets in the lamellar phase to form Janus nanosheets. DESCRIPTION OF DRAWING(S) - The drawing shows diagram of bi-phase and liquid-crystal lamellar phase. 102Bi-phase system 104Single oil-phase layer 106Single water-phase layer 108Liquid-crystal system 110lamellar phase
