摘　　要：Improving the adsorption efficiency of porous adsorbent materials for organic liquids with high viscosity is crucial for addressing oil spill incidents.In this study,a high-performance aerogel adsorbent composed of polyimide(PI),hydroxyapatite nanowires(HAPnws),and reduced graphene oxide(rGO)has been fabricated,which leverages reduced flow tortuosity through anisotropic structures and solar-assisted viscosity reduction via photothermal materials.The prepared anisotropic PI/HAP/rGO aerogel,with directional channels,shows unique mechanical properties with high stiffness along the axial direction and compressibility along the radial direction.
