Classification: CPC C  B | IPC B  C

Claim 0:
1. A salt water dispersed nanofluid, wherein the nanofluid comprises:
a dispersion comprising:
polyelectrolyte comprising poly sodium 4-styrenesulfonate (PSS);
amphiphilic Janus nanosheets comprising graphene oxide derivatized with at least one alkylamine group;
NaCl; and
CaCl2),

wherein the dispersion comprises at least 3.5 wt. % NaCl and at least about 0.5 wt. % CaCl2), and wherein the salt water dispersed nanofluid maintains a same interface behavior in brine as in fresh water, thus indicating colloidal stability.
