Mechanism of Wetting of a Nano-Suspension Droplet: Insights from MD Simulations




Abstract: Mechanism of wetting of nano-suspension droplets is discussed by results from Molecular Dynamics Simulations. We examine how wetting kinetics depend on the effects of nanoparticle size and interaction strength. Results demonstrate that increasing the particle size dramatically changes observed wetting behavior from depinning to pinning. Additionally, simulation results show how weakening the interaction between the particle and the underlying substrate can change a system from exhibiting pinning behavior to de-pinning.
