High-foam-stability and high-durability material suitable for high-altitude and low-air-pressure conditions as well as preparation method and application of high-foam-stability and high-durability material

The invention provides a high-foam-stability and high-durability material suitable for high-altitude and low-air-pressure conditions as well as a preparation method and application of the high-foam-stability and high-durability material. The high-foam-stability and high-durability material comprises a hydrophobic structure and a hydrophilic structure, the hydrophobic structure is graphene oxide, the hydrophilic structure comprises a plurality of hydrophilic chain segments connected to the graphene oxide through covalent bonds, and each hydrophilic chain segment is composed of an ethylene oxide unit and an ionic group unit. A plurality of hydrophilic chains of the high-foam-stability and high-durability material are connected to the surface of graphene oxide through covalent bonds, and the structure weakens the electrostatic repulsive force of a traditional single-chain air entraining agent when the air entraining agent is arranged on a gas-liquid interface, so that molecules are arranged more tightly and orde
