Title:Realization and Graph Representation of Impedance Network of a Graphene Nanoplatelet Nanocomposite
Author(s):Karimi, Pouyan
Subject(s):Mechanical Science and Engineering
Abstract:A realization of a nanocomposite including nanofiller is randomly generated using Blue Waters supercomputers. The left figure demonstrates a realization of a nanocomposite including oblate ellipsoids, graphene nanoplatelets (GNPs), for 2524 nanofillers. The fillers shown in magenta belong to the percolating cluster, while the fillers in cyan belong to other isolated clusters. The realization can be used to calculate impedance network of the nanocomposite. In the right figure, such network is shown for this realization. The red/green node represents the top/bottom electrode and all nanofillers that are in contact with top/bottom electrode. The edges show the mutual impedance between nanofillers (nodes). The brightness of the edges is proportional to the mutual impedance, lighter edges show larger mutual impedance magnitude. Using impedance network, electromagnetic properties and current path can be extracted. It provides a better understanding of current flow inside the nanocomposite, i.e. how current passes through the nanofillers and which nanofillers are part of the current path.
