a) Impact of the conformal pPFDA coating on the wettability of the patterned CNT micropillars. Left panel is the SEM image of the patterned CNT micropillars and right panel is the SEM imaging after wetting of the sample with water and drying. b) Utilizing nanoporous microstructures made of the pPFDA‐coated patterned CNTs as stamp for flexoprinting of electronic features on glass and PET substrates. The scale bar shown in the inset is 500 µm.
