Figure 4: Mechanical characterization of monolayer 2DP (4).

From: Wafer-sized multifunctional polyimine-based two-dimensional conjugated polymers with high mechanical stiffness

Figure 4

(a) Schematic depiction for the synthesis of the 2DP (1), transfer (2) onto a plain elastomeric substrate (PDMS), and transversal compression upon uniaxial lateral stretching of the 2DP on PDMS (3), inducing wrinkling for the monolayer. (b) AFM topography image of the wrinkled 2DP. The insert in b shows an amplified image of the wrinkles. (c) Integrated intensity profile after 2D Fourier-transformation (see insert) along kx direction revealing a mean periodicity of 152 nm. Scale bars in b and insert are 5 μm and 500 nm, respectively. a.u., arbitrary unit.
