Fig. 5. 2D and 3D printing of CNT structures.

Fig. 5.

(A) Schematic of 3D printing of CNT dissolved in 95 volume % pToS with 5 volume % oleum. (B) 2D direct write printed pattern of CNTs depicting the molecular structure of pToS on polyamide. (C) 3D-printed cylinder before coagulation. (D) SEM of a 3D-printed CNT log pile after coagulation, demonstrating the strong interlayer adhesion. Red and yellow arrows represent orthogonal print lines that have merged, and white arrowheads represent pores between print lines. (E) Focused ion beam cut cross section of a single print layer showing the porous aerogel structure.
