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. …
Webb8 maj 2024 · Most remarkably, unlike the spreading on non-SH surfaces, we witness that the spreading on SH surfaces is not dominated by the motion of the three-phase contact line (TPCL). Rather, the TPCL remains pinned at the edge of a nanopillar and the spreading is ensured by the liquid surface or the liquid–vapor interface (of this pinned TPCL) … WebbContact line, pinning Plot the shape of the contact line pinned to a defect using Eq.
