Fig. 4: Construction of CALF and investigations of its properties.
From: Large-scale conformal synthesis of one-dimensional MAX phases
a The enlargement of aligned ATAC nanofibers. b, Schematic illustration of synthesis mechanism for CALF. c SEM images of cross-section of CALF before and after polishing, showed continuous distribution of Cu along the stacking direction, while ATAC nanofiber matrix distributed between Cu layers. d Elemental mapping of cross-section of CALF shows the diffusion of Al atom and Cu atom. e Tensile stress−strain curves of 600 μm CALFs with different volume content of ATAC nanofibers constructed by stacking different thickness of Cu foils (20 μm, 35 μm, 90 μm and pure Cu foils). f Schematic illustration of crack mechanism for CALF. ATAC nanofibers were applied as fiber strengthen phase. g The linear increasement of tensile strength of CALF with increased volume content of ATAC. h, Coefficient of friction curves conducted from the cross-section of samples along different directions. i Comparisons of yield strength and electrical conductivity with other works38,40,45,51,52,53,54,55,56,57,58,59,60,61.
