SEM images of nanorod- and film-coated surfaces. SEM images of Cr films deposited onto HDPE substrates to thicknesses of a 50 nm and b 200 nm and Cr nanorods deposited onto HDPE substrates to nominal thicknesses of c 50 nm and d 200 nm. d The inset is an SEM image at a higher magnification to highlight the morphology of the coalesced Cr nanorods, where the scale bar is 1 μm
