Carbon nanotube(CNT)and graphene-based porous materials usually have low strength and stability,which severely limit their application fields.Here,we present a junction-welding approach to fabricate porous CNT solids in which all CNTs are coated and welded in situ by an amorphous carbon layer,forming an integral three-dimensional scaffold with fixed joints.The resulting CNT solids are robust,yet still highly porous and compressible,with compressive strengths up to 72 MPa,flexural strengths up to 33 MPa,and fatigue resistance(elastic recovery after 100,000 large-strain compression cycles at high frequency).
