Waterborne graphene-and nanocellulose-based inks for functional conductive films and 3d structures 2021 Access copy available to the general public Unrestricted In the vast field of conductive inks, graphene-based nanomaterials, including chemical derivatives such as graphene oxide as well as carbon nanotubes, offer important advantages as per their excellent physical properties. However, inks filled with carbon nanostructures are usually based on toxic and contaminating organic solvents or surfactants, posing serious health and environmental risks. Water is the most desirable medium for any envisioned application, thus, in this context, nanocellulose, an emerging nanomaterial, enables the dispersion of carbon nanomaterials in aqueous media within a sustainable and environmentally friendly scenario. In this work, we present the development of water-based inks made of a ternary system (graphene oxide, carbon nanotubes and nanocellulose) employing an autoclave method. Upon controlling the experimental variables, low-viscosity inks, high-viscosity pastes or self-standing hydrogels can be obtained in a tailored way. The resulting inks and pastes are further processed by spray-or rod-coating technologies into conductive films, and the hydrogels can be turned into aerogels by freeze-drying. The film properties, with respect to electrical surface resistance, surface morphology and robustness, present favorable opportunities as metal-free conductive layers in liquid-phase processed electronic device structures. info:eu-repo/grantAgreement/ES/DGA/E47-20R info:eu-repo/grantAgreement/ES/DGA/T03-20R info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-104272RB-C51/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MICINN/PID2019-104307GB-I00-AEI-10.13039-501100011033 info:eu-repo/grantAgreement/ES/MINECO/BES-2017-080020 info:eu-repo/grantAgreement/ES/MINECO-FEDER/ENE2016-79282-C5-1-R info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 5.719 2021 PHYSICS, APPLIED 37 / 161 = 0.23 2021 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 53 / 108 = 0.491 2021 Q2 T2 CHEMISTRY, MULTIDISCIPLINARY 55 / 179 = 0.307 2021 Q2 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 109 / 344 = 0.317 2021 Q2 T1 0.839 2021 Materials Science (miscellaneous) 2021 Q1 Chemical Engineering (miscellaneous) 2021 Q1 6.6 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Baigorri A.
