The conductivity of the nanocomposite increased rapidly and then stabilized when the CNT content was increased up to and beyond the percolation threshold. Various structures were created using a digital light processing (DLP) 3D printer. Various polymeric dispersants (SMA-amide) were designed and synthesized to improve the CNT dispersion and prevent aggregation. The benzene rings and lone electron pairs on the dispersant interacted with aromatic groups on the CNTs, causing the former to wrap around the latter. This created steric hindrance, thereby stabilizing and dispersing the CNTs in the solvent. CNT\/polymer nanocomposites were created by combining the dispersant, CNTs, and a photocurable resin. The CNT content of the nanocomposite and the 3D printing parameters were tuned to optimize the conductivity and printing quality. A touch-based human interface device (HID) that utilizes the intrinsic conductivity of the nanocomposite and reliably detects touch signals was fabricated, enabling the free design of sensors of various styles and shapes using a low-cost 3D printer. The production of sensors without complex circuitry was achieved, enabling novel innovations.<\/jats:p>","DOI":"10.3390\/polym15244706","type":"journal-article","created":{"date-parts":[[2023,12,14]],"date-time":"2023-12-14T03:58:02Z","timestamp":1702526282000},"page":"4706","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Photocurable Carbon Nanotube\/Polymer Nanocomposite for the 3D Printing of Flexible Capacitive Pressure Sensors"],"prefix":"10.3390","volume":"15","author":[{"given":"Jia-Wun","family":"Li","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ho-Fu","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng-Han","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9025-8755","authenticated-orcid":false,"given":"Chung-Feng Jeffrey","family":"Kuo","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1605-6338","authenticated-orcid":false,"given":"Chih-Chia","family":"Cheng","sequence":"additional","affiliation":[{"name":"Graduate Institute of Applied Science and Technology, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2258-2454","authenticated-orcid":false,"given":"Chih-Wei","family":"Chiu","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"676","DOI":"10.1021\/acsaelm.0c00841","article-title":"Facile fabrication of a stretchable and flexible nanofiber carbon film-sensing electrode by electrospinning and its application in smart clothing for ECG and EMG monitoring","volume":"3","author":"Huang","year":"2021","journal-title":"ACS Appl.
