adhesive force mimicking gecko’s foot.18 This material has been successfully applied to no lost reversible transport of microlitersized superparamagnetic liquid droplets by alternating magnetic fields.19 Generally, there are two superhydrophobic states on a rough surface: Wenzel’s state and Cassie’s ...
We recently clarified the definition of superhydrophobic surface as five states, in which lotus and gecko attribute to the special case of Cassie’s state. 20 Comparedwiththe lotus effect widelyobserved in the nature, less examples are known showing the adhesive property with an important Cassie ...
this means that 1W-SMPs can be programmed under a certain stress and temperature, and they can revert from a deformed shape to the permanent shape through reheating; however, without stress reassignment, 1W-SMPs cannot transform between the initial and temporary states[40–42]. On the other han...
United States Patent Application 20150273733 Kind Code: A1 Abstract: Superhydrophobic films and methods of making such films are disclosed. More particularly, superhydrophobic films having durable nanostructures with high contrast ratios and various methods of producing such films are disclosed....
a differentiation from the pure Wenzel states can still be made with both water bands vanishing from the spectrum. On the other hand, for very short structures, when the change in absorption intensities becomes comparable to the measurement errors, the two wetting states cannot be distinguished any...
200nm wide. This is enough to trap air below a water droplet placed on the surface. Ajayagosh says the work has shown that it is quite possible to chemically mimic the superhydrophobic states found in nature by creating differing surface morphologies. ‘We are not using any fluorinated chemist...
Free-energy barrier of filling a spherical cavity in the presence of line tension: implication to the energy barrier between the cassie and wenzel states on a superhydrophobic surface with spherical cavities Langmuir, 32 (2016), pp. 9475-9483 Google Scholar 71 H.Y. Guo, B. Li, X.Q. Feng...
The transition between the composite (Cassie) and wetted (Wenzel) states is a linear effect with the microdroplet radius proportional to the pitch over pillar diameter. It is shown that wetting of a superhydrophobic surface is a multiscale phenomenon that involves three scale lengths. Although the...
