Abstract
The spreading profiles of small (picoliter) droplets of polydimethylsiloxane on silver surfaces have been monitored in the thickness range below one monolayer. The profile shapes are distinctly non-Gaussian and can be approximated rather well by spherical caps. The experimental shapes and spreading dynamics are compared with Monte Carlo simulations of spreading polymer liquids. Excellent agreement is found.Keywords
