Fig. 4. Mechanical properties and wettability of the CNT-EP-PC15 membrane.

Fig. 4

a Stress vs. Strain curve measured by the standard tensile test. Inset: photographs of a CNT-EP-PC15 membrane and an ITO-EP-PC15 film fabricated on the dense ITO glass. b Photograph of the flexible CNT-EP-PC15 membrane; c Photograph of the CNT-EP-PC15 membrane holding a vial bottle and ten metal blocks. The total weight of the vial bottle and the metal blocks was about 8000-12000 times greater than the weight of CNT-EP-PC15 membrane itself. d AFM image showing the peak force quantitative nanomechanical mapping (PFQNM) curve. e The Young’s modulus profile along the PFQNM curve; and f Contact angle measurements of water (left) and methanol (right) on the CNT-EP-PC15 membrane.
