Single-walled carbon nanotube–amylopectin complexes

Single-walled carbon nanotubes (SWCNTs) are wetted in aqueous solution of pure potato and waxy corn amylopectins. Formation of weak sorption complexes of amylopectins on carbon nanotubes is postulated based on the micro-Raman spectra, differential scanning calorimetric and thermogravimetric studies as well as scanning electron micrographs and atomic force microscope images. Under an influence of ultrasounds bundles of SWCNTs disintegrated much more readily in aqueous solution of waxy corn amylopectin. In the solid state resulting from evaporation of suspensions to dryness interactions of SWCNTs with waxy corn amylopectin were also stronger than with potato amylopectin.
