“…26,27,29,48 It is reported in the literature that the advancing contact angle of pure COC surface is between 101-104 0 and the receding contact angle is between 82-86 0. 51,57,65 The difference between advancing and receding contact angles is described as contact angle hysteresis (CAH, Δθ = θ a − θ r ), which is caused by surface roughness and surface chemical heterogeneity. CAH values of COC SiO 2 nanocomposites with changing nanoparticle amount (% wt) for different coating temperatures are given in Figure 1 (b).…”

A superhydrophobic cyclic olefin copolymer (COC) nanocomposite coating was produced with a very simple and easy method. Self-cleaning superhydrophobic COC surfaces were obtained by only adding surface hydrophobized SiO 2 nanoparticles by dip coating method. The influence of concentration of SiO 2 and the coating temperatures on the wettability of the surfaces were investigated. The surface wettability of the coatings was examined with the contact angle measurements and the surface roughness and morphology were analyzed by using atomic force microscope and scanning electron microscopy analysis. Surfaces with certain amounts of COC and SiO 2 showed superhydrophobic character with high water contact angle of 169 0. Also, the obtained superhydrophobic surfaces show superior water repellent, high transparency, and self-cleaning characteristics.

“…Although there have been some reports on process for preparing superhydrophobic surfaces using anodic porous alumina as a starting structure, a process that can generate the superhydrophobic surface with precisely controlled surface geometrical structures has not been established so far. 24,25 The present process can be formed the precisely controlled hierarchical structures on a surface of substrates by nanoimprinting using anodic porous alumina molds. By optimizing the hierarchical structure of anodic porous alumina molds, the preparation of superhydrophobic surface having a contact angle greater than 170 could be realized.…”

Superhydrophobic materials are found in a suite of scientific and industrial applications, and given their broad potential use, there is great interest in facilitating their mass production. Although numerous methods have been used to produce superhydrophobic materials, only a few are capable of fabricating superhydrophobic surfaces and materials at an industrial scale. Techniques such as injection molding, compression molding, hot embossing, and polymer casting play an important role in the mass production of superhydrophobic polymer surfaces. This technical literature review summarizes recent advances in the polymer molding processes used to fabricate superhydrophobic materials. Here, we review replication methods and the materials that can be used by these approaches. We also evaluate the advantages and disadvantages of these methods and discuss the challenges of molding and demolding single-level structures (e.g., microstructures and nanostructures) and multilevel structures (e.g., micro-nanostructures, micromicrostructures, and micromicro-nanostructures), with a focus on superhydrophobic surfaces. We evaluate the relationship between structure geometry and the wettability of a surface, highlighting the effect of structure type and size in achieving the desired wettability. We then offer perspectives, discuss current limitations, and suggest required studies. This review aims to assist researchers in understanding the fundamentals related to the fabrication of patterned surfaces via polymer molding processes and offer avenues for the successful creation of superhydrophobic polymeric surfaces.
