The microstructures of multi-walled carbon nanotubes in agarose, epoxy and polypropylene have been imaged using confocal, optical and transmission electron microscopy with varying degrees of success. It can be beneficial to using imaging techniques with differing resolutions so that the full hierarchy of CNT structures can be appreciated.
