 The pore structure of the frit allows a rapid exit of the solvent leaving the carbon nanotubes to be pressed together.The presence of the solvent controls the interaction between the tubes allowing the formation of tube-tube junctions; its surface tension directly affects the overlap of adjoining nanotubes thus gaining control over the porosity and pore diameter distribution of buckypaper.The distribution of carbon nanotubes in solvent does not have to be a stable suspension, rather a general dispersion serves much easier to keep the nanotubes between the frits rather than pass through them.
