Claim 0:
1. A method for producing a colloidal aphron/graphene hybrid fluid composition, the method comprising:
forming a first mixture by mixing a graphene derivative solution and a biopolymer solution, the biopolymer solution comprising at least one of polyvinyl alcohol, carboxymethylcellulose, starch and starch derivatives, chitosan, hyaluronan, xanthan, hydroxypropyl cellulose, polyethylene glycol, polyanionic cellulose, poly(vinyl pyridine), hydrolyzed polyacrylamide, poly(acrylic acid), polyoxyethylene-polyoxypropylene block copolymer, and polyacrylamide, wherein the graphene derivative solution comprises graphene oxide, forming the first mixture further comprising forming a graphene oxide aqueous solution by mixing the graphene oxide and water in an ultrasonic device with an ultrasonic power in a range of 50 W to 100 W for 10 minutes to 30 minutes; and
forming a second mixture by mixing the first mixture with at least one of an ionic-surfactant solution and a non-ionic surfactant solution, the ionic-surfactant solution comprising at least one of sodium lauryl ether sulfate, linear alkylbenzene sulfonic acid, sodium dodecyl sulfate, sodium dodecylbenzene sulfonate, dodecyltrimethylammonium bromide, and cetyltrimethylammonium bromide, and the non-ionic surfactant solution comprising at least one of polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monopalmitate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan monooleate, sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan monooleate, polyoxyethylene octyl phenyl ether, and nonylphenol ethoxylates.
