In situ generation of 3D graphene-like networks from cellulose nanofibres in sintered ceramics

Establishing a 3D electrically percolating network in an insulating matrix is key to numerous engineering and functional applications. To this end, using hydrophobic carbon nanofillers is tempting, but still results in suboptimal performance due to processing challenges. Here, we demonstrate how natural cellulose nanofibres can be in situ transformed into graphene-like sheets connected to a 3D network enhancing both the transport and the mechanical properties of sintered engineering ceramics. The network architecture also permits the decoupling of electrical and thermal conductivities, which represents a major obstacle in attaining efficient thermoelectric materials. We foresee that our transferable methodology can pave the way for the use of natural nanofibres to unravel the full potential of 3D graphene-like networks to accelerate development in fields like energy and telecommunications.Financial support from the Slovenian Research Agency (research core funding No. P2-0087) and the Spanish Ministry of Economy and Competitiveness (CYCIT, MAT2012-31759, MAT2015-71117-R, MAT2014-52405-C2-2-R) is acknowledged as well as from the EU Horizon 2020 research and innovation program under grant agreement No. 696656 (Graphene Core1-Graphene-based disruptive technologies).
