In this work, we prepared homogeneously dispersed carbon nanotubes in water using a high‐pressure homogenizer, while high‐density carbon nanotube buckypapers were prepared by wet‐laid process. The strength and conductivity of the buckypaper were increased dramatically after the high‐pressure homogenization because of the increased density and uniformity of the paper. In addition, the buckypapers containing various additives and treated with SOCl 2 exhibited further increase of strength and conductivity resulting from the binding and the p ‐type doping effect. The buckypapers with high electrical conductivity exhibited superior electromagnetic interference shielding effectiveness that could be applied for structural shielding materials.
