3-D profile of coffee ring effect (CRE) for high concentration solution containning polystyrene (PS) nanoparticles (NPs) on low-adhesion superhydrophobic (LASH) surface.
The contact angle (CA) and slide angle (SA) of the LASH surface are 161.2° and 2°, respectively. The volume of the solution is 10 μL and the concentration is 10 mg/mL. The outer diameter, inner diameter and average height of the deposited ring are 927.49 μm, 261.47 μm, and 231.52 μm respectively.
