“…Inspired by surface engineering found in nature, and using the concepts provided by the Wenzel and Cassie-Baxter models of wetting [8,9], the methodologies for preparing superhydrophobic surfaces can be generally categorized into the 'top-down' and 'bottom-up' approaches as a first step to create a specific surface roughness. Top-down approaches encompass lithographic and template-based techniques [10], laser ablation technique [11] and plasma treatment of the surfaces [12,13]. Bottom-up approaches mostly involve self-assembly and self-organization [14], such as chemical bath deposition (CBD) [15,16], chemical vapor deposition (CVD) [17] and electrochemical deposition [18].…”

Superhydrophobic thin films of silver were fabricated on copper substrates by galvanic ion exchange reactions in a one-step process by immersing copper substrates in silver nitrate solution containing fluoroalkylsilane in different quantities. The X-ray diffraction (XRD) analyses confirmed the formation of silver films on copper substrates and the fractal-like morphological features of the silver films were confirmed using scanning electron microscopy (SEM). The contact angle of water on these surfaces is found to be greater than 165•, demonstrating water repellency with water drops rolling off the surfaces. The X-ray photoelectron spectroscopy (XPS) depth profile confirms the presence of fluorine in the silver films.

The adhesion between a micro-object and a microgripper end-effector is an important problem in micromanipulation. Canceling or reducing this force is a great challenge. This force is directly linked to the surface chemical structure of the object and the gripper. We propose to reduce the adhesion force by using a self-assembled monolayer structuring on one surface. The surface was structured by polystyrene latex particles (PS particles) with radii from 100 to 1500 nm. The adhesion force measurements obtained by AFM were compared to a multisphere van der Waals force model. The model suggests the existence of an optimal value of the sphere radius which minimizes the adhesion. In that case, the pull-off force is reduced to 20 nN by the PS particles layer with a radius of 45 nm. A wide range of applications in the field of telecommunications, bioengineering, and more generally speaking, MEMS can be envisaged for these substrates.

“…[40][41][42] With different plasma deposition techniques also contact angles of water in the range of 150° to 170° are reached on textile substrates. 43,44 In this technique the type of monomer used for plasma deposition is significant for the gained hydrophobic effect. Suitable monomers are here hexamethyldisiloxane HMDSO and tetrafluoromethane CF 4 .…”

“…Suitable monomers are here hexamethyldisiloxane HMDSO and tetrafluoromethane CF 4 . 43,44 Such high contact angle values are often summarized under the terms superhydrophobic properties or superhydrophobic textiles. [45][46][47] Therefore, in relation to other hydrophobic recipes for textile treatment the actual developed Tung Oil recipe can be ranked in the range of moderate hydrophobic agents but not used for realization of superhydrophobic textiles.…”

A treatment for hydrophobic functionalization of natural fiber materials is developed. This hydrophobic treatment is based mainly on natural products. As hydrophobic component the natural Tung Oil is used, which is originally a compound used for wood conservation purposes. The application on textile is done in a padding process under presence of an oxidative agent. For the current investigations a fiber felt from linen was used. The hydrophobic effect is determined by the concentration of Tung Oil and the duration of a thermal drying process. The hydrophobic effect is investigated by capillary rise tests and contact angle measurements. Scanning electron microscopy SEM is used to investigate the surface topography of the fiber material and the deposited hydrophobic material. Altogether, an interesting and promising method for hydrophobisation of natural fibers is developed, which could especially be used as part of a production process of a fiber reinforced composite material, mainly based on natural products.
