Abstract
Graphite nanoplatelets (GNPs) can be included in very low weight percentages in a polymer matrix to create new lightweight nanocomposites with desired electromechanical properties, for application in strain sensors. The development of simulation models for the prediction of the electromechanical characteristics of such composites is very important for design and performance optimization purposes. In this study we propose an electromechanical model for the prediction of the response of a strain sensor made of GNP-filled composite. The developed simulation approach is based on the tunneling-percolation model of the electrical transport in the composite, and on the experimental characterization of the dc conductivity of GNPs and GNP-filled composites at different concentrations, produced in the CNIS Labs of Sapienza University. © 2011 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
