WebbIn the often encountered regimes of low contact angles, evaporation time of a (printed) droplet with pinned contact line can be expressed, following Popov [95], as (9.14) where is the pinned contact diameter, is the liquid density, its molecular weight and is the diffusion coefficient of the liquid vapor at a temperature T into the surrounding air. Webb11 jan. 2013 · Colloidal particles suspended in a fluid usually inhibit complete wetting of the fluid on a solid surface and cause pinning of the contact line, known as self-pinning. We show differences in spreading and drying behaviors of pure and colloidal droplets using optical and confocal imaging methods.
