Fig. 1: The morphology and elemental distribution of ZIF-67 and the F-ZIF-67/PDMS films.
From: Design of F-ZIF-67/PDMS-based triboelectric nanogenerator for enhanced cathodic protection

a SEM of ZIF-67 powder, the inset Fig. showed the low magnification, b Elemental color mapping of ZIF-67 showed the distribution of different elements, c EDS spectra with the corresponding atomic percentages of elements in ZIF-67. d SEM of F-ZIF-67/PDMS composites with varying ZIF-67 weight percentages.
