Representative SEM and TEM micrographs for 1:4 MWCNT films. (A) Overview micrograph of crosslinked MWCNT coating with a cross-sectional inset in the upper right (scale bar 100 μm). Red line denotes the surface-nanomaterial interface. (B) Junctions between nanotubes, shown in red oval (B) and magnified in (C) and (D), suggest crosslinking. (E) TEM image of a single crosslink junction with (F) the directions of intersecting MWCNT lattice shown by red arrows.
