Abstract:

A facile noncovalent surface modification method for multi-walled carbon nanotubes(MWNTs) through soluble starch to be prearranged helical state produced by complexing with silver colloid was described. The starch modified MWNTs show great ease of exfoliation into water and SEM analysis shows a significant debundling upon silver colloid treatment. Amylatic reaction, IR and EDS analysis indicate the MWNTs surface modification by soluble starch.
