Atomic layer deposition (ALD) of ZnO on MWCNT. a Schematic of ALD on a generic surface. Reactants are introduced sequentially to build one self-limiting monolayer of material at a time. b ZnO thickness and material weight gain increase linearly with the number of ALD cycles. c TEM micrographs of MWCNT, uncoated and coated, show tube length decreases following sonication. Higher magnification images show conformal coating
