Morphological and chemical analyses of the nanotubes (HNTs, Halloysite, Dragonite HP) with and without CHX. (a) Representative TEM micrograph of the as-received HNTs. (b) Inset high-magnification TEM micrograph showing the uniform rod-like tubular structure, the hollow nature, and the morphological aspect of the tubes (scale bar = 100 nm). (c) ATR-FTIR spectra for pristine HNTs, CHX, and CHX-loaded nanotubes.
