Le corps d'aérogel composite comprend une couche supérieure hydrophobe et une couche inférieure hydrophile, la couche supérieure étant un aérogel de MXene constitué de nanofibrilles de cellulose modifiées par des silanes/Ti3C2Tx, la couche inférieure est un aérogel de nanofibrilles de cellulose, l'interface entre la couche supérieure et la couche inférieure est reliée dans son ensemble par un effet de réticulation chimique, plusieurs trous traversants sont formés à l'intérieur du corps d'aérogel composite, et les trous traversants pénètrent intégralement dans la couche supérieure et la couche inférieure du corps d'aérogel composite. Du fait d'une caractéristique Janus d'une partie supérieure hydrophobe et d'une partie inférieure hydrophile de l'aérogel composite, l'aérogel composite peut flotter indépendamment et de manière stable au niveau d'une interface air-eau, la moitié inférieure de l'aérogel composite absorbe complètement l'eau et est immergée dans l'eau, et la moitié supérieure de celui-ci est maintenue sèche et exposée à l'air. De plus, du fait que les couches supérieure et inférieure de l'aérogel composite sont reliées entre elles par une action chimique, il n'y a aucun espace entre elles, ce qui empêche la chaleur de se dissiper vers l'extérieur par un espace, et la chaleur de la couche supérieure peut être efficacement utilisée pour l'évaporation de l'eau.
