Characterization of pNE surfaces. (a) Surface wettability is measured by a goniometer. The symbol indicates a significant difference compared to each unmodified substrate (). (b) Representative digital images of pNE-coated PTFE, PDMS, glass, and TCP substrates. The dark brown colors indicate pNE coating. (c) Topographical images of pNE interfaces using AFM analysis.
