Reduced graphene oxide/ poly(dimethylsiloxane) composites for use in finger-sensing piezoresistive pressure sensors |
| 초록 |
We fabricated a piezoresistive composite using reduced graphene oxides (RGOs) as a conductive filler and polydimethylsiloxane (PDMS) as a polymer matrix. To achieve a homogeneous dispersion of RGOs in PDMS, the RGOs were modified by covalent functionalization using hydrazine derivatives. The percolation threshold and electrical resistivity of the composites was significantly lowered compared to that of graphite/PDMS composite. The well-dispersed RGOs/PDMS composite showed good piezoresistive characteristics in extremely small pressure range required for finger-sensing. |
