Percolation in Suspensions of Rod-like Colloids under Shear Flow — •Victor Tänzel, Fabian Coupette, and Tanja Schilling — Institute of Physics, Albert-Ludwigs-University Freiburg, Germany

Suspensions of electrically conductive fillers are an interesting class of material for applications in energy storage and sensor technology. Their practicality depends on the behavior of the fillers, which is intricate and complex for elongated particles in flow.

We use multi-particle collision dynamics (MPC) to model rod-like particles in shear flow of a hydrodynamic medium. Percolation and conductivity are characterized with regard to the system's properties. MPC also allows us to turn off the hydrodynamic interactions from the solvent, so we can assess their influence.

Keywords: percolation; multi-particle collision dynamics; shear flow; conductivity; rod-like particles
