We demonstrated that the nanopores of carbon materials could be reversibly deformed upon external pressurization up to 500 MPa and that the elastic properties are supported by quasi-linear stress-strain curves with nearly no loss in energy. In the presence of water or alcohol vapor, the gas-liquid equilibrium is significantly and compulsively altered upon deformation of the nanopores (Fig. ). This phenomenon could be used for refrigeration based on mechanical-force-induced phase transition of adsorbate (RMPTA) systems. NPGs with small Y values are a promising class of materials for RMPTA combined with water and alcohols as environmentally friendly adsorbates because the coefficient of performance (COP) is proportional to the reciprocal of Young's modulus of the material (Y -1 ). Slow diffusion of molecules is a general issue related to the application of porous materials, but ideal 3D graphene materials with structural regularity can achieve fast diffusion of gases and a more flexible 3D continuous graphene structure simultaneously.
