Fig. 2: Mechanical properties of BNNS-TIMs.

A Tensile stress–strain curve of specimens with filler loadings of 50–90 wt%. B SEM images of the fracture section of specimens with (B1–B2) 50 wt% and (B3–B4) 90 wt.% loadings. The scale bars for B1 and B3 are 200 μm, and for B2 and B4 are 20 μm. C and D FEM simulation that shows the C instant stress and D cumulative strain distribution in specimens with 50, 70, and 90 wt% loadings under an external shear force.
