“…For example, the liner surface of type IV vessels are not limited by vacuum chamber sizes. [ 35 ] Therefore, the most significant advantage of this approach is simplicity of combining it with mass production applications. [ 36 ] Plasma SPA2800H (atmospheric‐pressure plasma system (Figure 2), Dongguan Shengding Precision Instrument Co., Ltd.) was used to treat the surface of PA11 liners in the study.…”

Weak interfacial bonding properties between thermoplastic liners and carbon fiber‐reinforced composites (CFRP) can easily lead to debonding failure, which is a major challenge in development of type IV composite hydrogen storage vessels. We optimized Box–Behnken design atmospheric‐pressure plasma process parameters for maximizing interfacial bonding properties between thermoplastic liner (PA11 liner) and CFRP using Design‐Expert software. From various designs, plasma process parameters, including time (t), nozzle‐to‐specimen distance (d) and gas flow rate (r) of treatment were selected for optimization to assess the effects of their interactions on climbing drum peel (CDP), flatwise tensile (FWT) and asymmetric double cantilever beams (ADCB). The CDP strength, FWT strength and strain energy release rate (GADCB) of untreated samples were 4.2 N·mm/mm, 0.26 MPa and 87.2 J/m2, respectively. After the plasma treatment, optimum process parameters of t = 200 s, d = 12.5 mm, and r = 700 L/h were used to achieve 33.8 N·mm/mm, 2.97 MPa and 1008.4 J/m2, respectively, which were 8.0, 11.4 and 11.6 times that of untreated PA11 surface, respectively. This method has the potential for guiding thermoplastic liner surface treatment of type IV hydrogen storage vessels before winding.

“…These unsuccessful attempts to achieve superhydrophobicity via replication can be explained by an inappropriate selection of structure size, a low aspect ratio of the structures, and demolding issues that resulted in a poor replication quality.

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.

“…Such surfaces require a low surface energy ultrathin layer combined with appropriate hierarchical micro–nanoroughness (i.e., dual-scale topography). Atmospheric pressure plasma etching/nanotexturing shows great potential to induce the proper hierarchical topography that will lead to superhydrophobic behavior after coating with a low surface energy thin film or monolayer. , We have previously proved this potential using paper as substrate, which is a composite-like material composed of cellulose fibers and inorganic (calcite) particles. After oxygen-rich plasma etching in atmospheric pressure we realized an enhanced surface topography and superhydrophobicity, due to the selective etching of organic over inorganic phase followed by deposition of a Teflon-like ultrathin film …”

We present the concept of the combined synthesis of organic−inorganic nanocomposite coatings and atmospheric pressure plasma etching/nanotexturing for tailoring the surface topography and fabricating multifunctional surfaces. As demonstration, we fabricated superhydrophobic ZnO/poly(methyl methacrylate) (PMMA) nanocomposite coatings. Composite coatings differing in ZnO content were synthesized and plasma etched in a dielectric barrier discharge operating in He/O 2 in an open-air environment. The phase selective plasma etching of organic over inorganic matter resulted in the gradual revealing of the inorganic ZnO particles, which were multisized due to agglomeration during the synthesis and plasma etching process. The creation of hierarchical topography led to the fabrication of roll-off superhydrophobic surfaces with water contact angle ∼158°and sliding angle ∼3°after the application of a low-pressure plasma deposited Teflon-like film. Moreover, we studied the optical properties of the superhydrophobic, atmospheric plasma nanotextured surfaces in terms of reflectance measurements (total, diffuse, and specular) to evaluate their possible use as antireflective surfaces.
