<p>Superhydrophobic surfaces (SHSs) require a combination of a rough nano- or microscale structured surface topography and a low surface energy. However, its superydrophobicity is easily lost, even under relatively mild mechanical abrasion, when the surface is mechanically weak. Here, we develop a method that significantly increases the mechanical durability of a superhydrophobic surface, by introducing a mesh layer beneath the superhydrophobic layer. The hardness, abrasion distance, flexibility and water-jet impact resistance all increase for the commercially available Ultra-ever Dry superhydrophobic coating. This is attributed to the increased mechanical durability offered by the mesh, whose construction not only increases the porosity of the SHS coating but acts as a third, larger structure, so that the superhydrophobic layer is now composed of a three-level hierarchical structure: the mesh, micropillars and nanoparticles.</p>

Optically Transparent

Transparent antennas are meant for their optical transparency. This paper analyzes the rectangular patch antenna designed using meshed conductors and solid ground planes. Meshing the antennas makes it as optically transparent and the antenna’s transparency is based on the mesh geometry. Even there is a tradeoff between the antenna’s efficiency and the visual seethrough ability of the patch antenna with meshed structure, it is able to tune the antenna by refining mesh lines. Material handling, fabrication process and the increased impedance are the important factors limiting the refining of the mesh lines, which also cause loss in efficiency of the antenna. Both the performance and antenna transparency is improved by a mesh refined with small line width (q). Also, by removing certain mesh lines, the antenna transparency is improved without affecting the antenna efficiency. This paper briefly explains the relation between the gain, transparency and the mesh structure of the antenna.

Injection Moulding Process

The lotus effect known from nature has so far only been successfully imitated by the incorporation of additives or by modifying the polymers used. By using microstructured moulds there is now a way to produce durable, superhydrophobic surfaces in a single-step injection moulding process. This method combines shaping and functionalisation of the part in one process step. The studies show that, by selecting suitable microstructures, an increase in the contact angle by up to 40° can be achieved. At the same time, the LSR microstructures produced show good abrasion resistance.
