High-performance graphene-based carbon nanofiller/polymer composites for piezoresistive sensor applications
Abstract
Poly(vinylidene fluoride) (PVDF) composites with different carbonaceous nanofillers, prepared by solution casting, were studied their chemical, mechanical, electrical and electro-mechanical properties evaluated. Few-layer graphene (FLG) nanoplatelets (G-NPL), graphene oxide (GO) and reduced graphene oxide (rGO) and single-walled carbon nanohorns (SWCNH)) were found to have a strong influence in the overall properties of the composites prepared with up to 5 wt% nanofiller contents. The mechanical strainof carbonaceous nanofillers/PVDF composites decreases from 15% to near 5% of maximum strain. The electrical percolation threshold depends on the nanofiller type, being below 1 wt% for rGO and near 2 wt% for the remaining nanofillers. The electrical conductivity shows a maximum increase of nine orders of magnitude, from σ ≈ 5×10-11 S/m of pure PVDF to σ ≈ 1×10-2 S/m for rGO/PVDF composites with 5 wt% nanofillers, the conduction mechanism being related to hopping between the carbonaceous nanofillers for concentrations higher than the percolation threshold. Furthermore, the composites show electro-mechanical properties, except for G-NPL materials, with rGO/PVDF composites with 5 wt% nanofiller content showing higher Gauge factor (GF) values, reaching GF≈ 11 for deformations between 0.5 and 2mm in 4-point bending experiments. These results demonstrate the suitability of the composites for strain sensing applications. ; Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UID/FIS/04650/2013, project PTDC/EEI-SII/5582/2014, grants SFRH/BPD/110914/2015 and SFRH/BD/98219/2013 (P.C. and J.O., respectively), as well POCH and European Union.
