This research addresses the critical demands in national defense, aerospace, and advanced thermal conductive material fields, and develops ordered macroscopic carbon nanotube film assemblies with important application values. The core objectives include fabricating carbon nanotube films with high density (1.59 g cm⁻³), high thermal conductivity (558.06–700.15 W m⁻¹ K⁻¹), high electrical conductivity (4870 ± 150 S cm⁻¹), high mechanical strength (2.74–2.95 GPa) and high Young's modulus (55.2–58.9 GPa). This work provides an effective strategy for developing advanced thermal conductive materials with high mechanical strength for applications under harsh conditions. We have developed an evaluation technique for the service performance of ordered macroscopic functional materials and devices under extreme conditions, and established a corresponding database. This dataset mainly covers the preparation, structural characterization, mechanical and physical property data, and materials of macroscopic carbon nanotube film assemblies.
