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.

In the embodiments of this application, the method includes: A projection transmit end obtains network status information, and determines a target resolution of an image to be projected based on the network status information; and then determines a to-be-synthesized layer based on whether the image is in a full-screen scenario.

In addition, a projection receive end can perform super-resolution on the image, to avoid image quality damage caused by reducing the amount of data sent by the transmit end. This solution reduces the projection delay and ensures projection image quality to improve user experience.
