Carbon nanotubes are generally synthesized in a fine powder with a very high specific volume and a low apparent density, which render their manipulation extremely difficult and hazardous. Here we demonstrate a simple and reliable method for the direct synthesis of multi-walled carbon nanotubes (MWCNTs) supporting each other in a controlled macroscopic shape and size by applying an external constraint on the reactor during the synthesis. The MWCNTs are highly entangled allowing a natural compacting of the macroscopic pieces without fine formation, making subsequent handling easier. The present synthesis method addresses many critical problems encountered with the use of carbon nanotubes as a macroscopic building-block materials.
