We study the potential of the 0D nanoparticles for improving electrical properties of the conductive MWCNT network in a biocompatible matrix. Physicochemical effects of fillers content, both individually and in combinations (MWCNTs\/C60 and MWCNTs\/C60(OH)24), for these composite systems, have been investigated. The performed SAXS analysis shows improved nanofiller dispersion for films with two fillers. The electrical percolation threshold (Pc) in MWCNTs composites occurs at \u22481.0 wt.%. A synergistic effect for binary filler composites on the electrical conductivity has been evaluated by keeping a constant amount of 0.5 wt.% MWCNTs (\u03c3 \u2248 3 \u00d7 10\u22129 S\u00b7m\u22121) and increasing the amount of C60 or C60(OH)24. A large increase in the electrical conductivity is obtained for the bifiller composites with 0.5 wt.% MWCNTs and 1.5 wt.% of C60(OH)24, reaching \u03c3 \u2248 0.008 S\u00b7m\u22121. Further, the sensing properties of 4.0\/1.0 MWCNT\/C60 nanocomposites were demonstrated by measuring both piezoresistive (PR) and thermoresistive (TR) responses. The combination of semiconductive fullerene\/fullerenols combined with MWCNTs allows obtaining more homogeneous composites in comparison to single MWCNTs composites and also gives possibilities for tuning the electrical conductivity of the system. Overall, it is demonstrated that the use of bifillers with a water soluble biopolymeric matrix allows the development of eco-friendly high-performance electroactive materials for sustainable digitalization.<\/jats:p>","DOI":"10.3390\/polym17243259","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T09:17:36Z","timestamp":1765185456000},"page":"3259","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Synergetic Effect of Fullerene and Fullerenol\/Carbon Nanotubes in Cellulose-Based Composites for Electromechanical and Thermoresistive Applications"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9092-7947","authenticated-orcid":false,"given":"Ane","family":"Mart\u00edn-Ayerdi","sequence":"first","affiliation":[{"name":"BCMaterials, Basque Center for Materials, Applications and Nanostructures, UPV\/EHU Science Park, 48940 Leioa, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3605-1937","authenticated-orcid":false,"given":"Timur","family":"Tropin","sequence":"additional","affiliation":[{"name":"BCMaterials, Basque Center for Materials, Applications and Nanostructures, UPV\/EHU Science Park, 48940 Leioa, Spain"},{"name":"European Molecular Biology Laboratory, 22607 Hamburg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1768-4528","authenticated-orcid":false,"given":"Nikola","family":"Pe\u0159inka","sequence":"additional","affiliation":[{"name":"BCMaterials, Basque Center for Materials, Applications and Nanostructures, UPV\/EHU Science Park, 48940 Leioa, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0188-4579","authenticated-orcid":false,"given":"Jos\u00e9 Luis","family":"Vilas-Vilela","sequence":"additional","affiliation":[{"name":"BCMaterials, Basque Center for Materials, Applications and Nanostructures, UPV\/EHU Science Park, 48940 Leioa, Spain"},{"name":"Innovative Macromolecular Materials Group (Imacromat), Physical Chemistry Department, Faculty of Science and Technology, University of the Basque Country UPV\/EHU, 48940 Leioa, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9887-0925","authenticated-orcid":false,"given":"Pedro","family":"Costa","sequence":"additional","affiliation":[{"name":"Physics Centre of Minho and Porto Universities (CF-UM-UP), Laboratory of Physics for Materials and Emergent Technologies, LapMET, University of Minho, Campus of Gualtar, 4710-057 Braga, Portugal"},{"name":"IB-S Institute of Science and Innovation for Sustainability, Universidade do Minho, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9315-4188","authenticated-orcid":false,"given":"Vasil M.","family":"Garamus","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Hereon, 21502 Geesthacht, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7945-2218","authenticated-orcid":false,"given":"Dmytro","family":"Soloviov","sequence":"additional","affiliation":[{"name":"European Molecular Biology Laboratory, 22607 Hamburg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6532-8902","authenticated-orcid":false,"given":"Viktor","family":"Petrenko","sequence":"additional","affiliation":[{"name":"BCMaterials, Basque Center for Materials, Applications and Nanostructures, UPV\/EHU Science Park, 48940 Leioa, Spain"},{"name":"Ikerbasque, Basque Foundation for Science, 48009 Bilbao, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6791-7620","authenticated-orcid":false,"given":"Senentxu","family":"Lanceros-M\u00e9ndez","sequence":"additional","affiliation":[{"name":"BCMaterials, Basque Center for Materials, Applications and Nanostructures, UPV\/EHU Science Park, 48940 Leioa, Spain"},{"name":"Physics Centre of Minho and Porto Universities (CF-UM-UP), Laboratory of Physics for Materials and Emergent Technologies, LapMET, University of Minho, Campus of Gualtar, 4710-057 Braga, Portugal"},{"name":"Ikerbasque, Basque Foundation for Science, 48009 Bilbao, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2610","DOI":"10.1002\/pat.5717","article-title":"Tuning Magnetorheological Functional Response of Thermoplastic Elastomers by Varying Soft-Magnetic Nanofillers","volume":"33","author":"Tubio","year":"2022","journal-title":"Polym.
