Electro-Mechanical properties of Inkjet-Printed graphene oxide nanosheets

Abstract : This study deals with the deposition of graphene oxide (G-O) thin films by inkjet printing method on Love wave devices, forming up G-O nanosheets in between the inter-digitated transducers (IDTs) of the device. Experimental results were compared with 3D finite element calculations. Enhanced properties were observed by amalgamating ultra-thin G-O films with SiO2 and lead to optimized guided surface acoustic wave propagation. The structural model of the G-O films provided useful information regarding the Young and the Shear modulus of the device, which are found near 470 and 196 GPa, respectively. The resulting Maxwelian viscoelastic components of G-O sheets were compared theoretically and experimentally to each other based on the providing losses on the Love wave devices through the scattering parameters (S-parameters). Similarly, the theoretical and experimental resonance frequency data showed a very good agreement. This behavior is attributed to the different mechanisms, thus combining the viscoelastic and gravimetric effects of the G-O on the Love wave devices. Finally, The G-O film was characterized using colocalized AFM/Raman imaging in order to assess its roughness and chemical homogeneity.
