Quantifying High-Performance Material Microstructure Using Nanomechanical Tools with Visual and Frequency Analysis

Figure 7

(a) UHMWPE greyscale AFM stiffness map of internal surfaces of S1000, S3000, and SK76 commercial fibers, where the darker shading is the more complaint, disordered material and the lighter shading is the stiffer, more crystalline material. (b) Duplicate stiffness maps of the ones above are shown, with lamellae highlighted in red by the spatial derivative of stiffness.
