Lim, D. D., Lee, J., Park, J., & Choi, W. (2022). High-resolution and electrically conductive three-dimensional printing of carbon nanotube-based polymer composites enabled by solution intercalation. Carbon, 194, 1-9.

Research Highlights

• Solution intercalation improves dispersion quality of MWCNT nanocomposite resin.

• Stereolithography employing the resin enables highly precise and conductive backbones.

• 0.6-wt% MWCNT in the nanocomposite show an electrical conductivity of 0.071 S/m.

• 3D-printed objects maintain a high dimensional accuracy verified with the IT grade.

• Complex 3D metamaterial and multi-scale capacitive sensors demonstrate the manufacturing capability.
