in this work the synthesis of polyaniline/chitosan/functionalized single- walled carbon nanotube nanocomposite is carried out. for this purpose single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. in other step, aniline monomers and chitosan were polymerized in the presence of iron (iii) chloride to sy...

Background and purpose: Cadmium is a very toxic metal that have adverse effects on human health and aquatic environments even at low concentrations, therefore, efforts should be made to eliminate this metal from aquatic ecosystem. The aim of this study was to investigate the efficacy of L-cysteine functionalized single-walled carbon nanotubes in removing cadmium from aqueous environments. This ...

Separating functionalized single-wall carbon nanotubes (SWCNTs) from functionalized amorphous carbon is challenging, due to their polydispersity and similar physicochemical properties. We describe a single-step, dialytic separation method that takes advantage of the ability of heavily functionalized SWCNTs to bundle in a polar environment while maintaining their solubility. Experiments on funct...

The electrical conductance response of single ZnO microwire functionalized with amine-groups was tested upon an acid pH variation of a solution environment after integration on a customized gold electrode array chip. ZnO microwires were easily synthesized by hydrothermal route and chemically functionalized with aminopropyl groups. Single wires were deposited from the solution and then oriented ...

Single-walled carbon nanotubes (SWCNT) functionalized with amino groups were prepared via chemical modification of carboxyl groups introduced on the carbon nanotube surface. Two different approaches (amide and amine-moieties) were used to produce the amino-functionalized nanotubes. The aminotermination allows further chemistry of the functionalized SWCNTs and makes possible covalent bonding to ...
