Abstract

Synthesizing 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.

Claims (8)

1. A nanoreactor comprising graphene oxide (GO) nanosheets at an interface between a water layer of a lamellar phase and an organic layer of the lamellar phase and functional agents, the nanoreactor is used to form Janus GO nanosheets from the GO nanosheets and the functional agents.

2. The nanoreactor of claim 1 , wherein the lamellar phase comprises at least 100,000 lamellar units.

3. The nanoreactor of claim 1 , wherein the lamellar phase comprises at least 100,000 nanoreactors.

4. The nanoreactor of claim 1 , wherein the nanoreactor comprises the water layer and the organic layer.

5. The nanoreactor of claim 1 , wherein the organic layer comprises an oil layer.

6. The nanoreactor of claim 1 , wherein the functional agents comprise silane-based chemical reagents.

7. The nanoreactor of claim 1 , wherein the lamellar phase comprises a nonionic surfactant.

8. The nanoreactor of claim 1 , wherein the lamellar phase comprises an anionic surfactant or a cationic surfactant.
