Elasticity profiles of electrospun membranes. DMT modulus images of electrospun PCL and PCL/gelatin fibers: PCL/CHCL3 (A), PCL/HFIP (B), PCL/gelatin/HFIP (C), PCL/gelatin/TFE (D). Scan size 5 μm × 5 μm, scale bar 2GPa. DMT modulus reflects the elasticity of the samples. It is determined by how the tip responds to the surface, and it measures the oscillations of the tip, which change depending on the surface it interacts with.
