Abstract

Preparation of multiwalled carbon nanotube-layered double hydroxide (MWCNT-LDH) nano-composites by (i) the co-precipitation of LDH components and pristine or surface-treated MWCNT or (ii) the delamination of LDH and application of the layer-by-layer technique has been attempted. For MWCNT, two types of surface treatment were used, either the surface was hydroxylated and deprotonated or wrapped in a tenside (dodecylbenzenesulfonate, DBS). LDH was delaminated by N,N-dimethylformamide. The obtained materials were characterized by X-ray diffractometry (XRD), and by scanning and transmission electron microscopies (SEM and TEM). Element distribution was mapped with help of the X-ray energy dispersive spectroscopy (XEDS) available as an extension of the scanning electron microscope. MWCNT could not be sandwiched between the layers of LDH by any of the methods employed; however, tenside-treated bundles of MWCNT could be wrapped in LDH thus forming a nanocomposite.
