Effect of functionalization of carbon nanotubes on the radar-absorbing properties of polymeric composites based on them

The effect of functionalization of carbon nanotubes in a mixture of sulfuric and nitric acids on the radar-absorbing properties of polymeric composites based on them was studied. The optimum functionalization conditions were determined, allowing the thickness of the radar-absorbent material to be decreased by 36–46% (with its characteristics preserved) relative to the analogous composites with unmodified nanotubes.
