Abstract: Disclosed is an amphiphilic graphene oxide (GO) temperature-resistant foam stabilizer for maintaining a wide pH range and a preparation method thereof. The amphiphilic GO is produced by dispersing GO in an ice-water bath, then sequentially adding a graphene oxide dispersion liquid, solid paraffin, emulsifier, and intercalation agent using a template method for emulsification and solidification. After washing and filtration, GO-coated paraffin microspheres are obtained. The microspheres are treated with hydrolyzed silane coupling agent, and further reacted with an amino modifier. GO-coated paraffin microspheres are dissolved completely in chloroform, followed by multiple centrifugation washes and freeze-drying to yield the foam stabilizer. The foam stabilizer has improved foam stability under high-temperature conditions across a wide pH range. It also possesses favorable interfacial activity and demonstrates a synergistic foaming effect with foaming agents.
