“…These phase-separation methods are known to be rapid, simple, and cost effective processes for creating rough superhydrophobic surfaces. [18][19][20][21][22][23][24] For example, polypropylene can be dissolved in an organic solvent and spread onto a solid surface, which creates a hierarchical superhydrophobic surface after the solvent is evaporated. 25 In these processes, the solvents and temperature are important factors for controlling the surface roughness and achieving superhydrophobicity.…”

“…Therefore, the large water contact angle (CA) of the lotus leaf, on the order of 160 • , is attributed to the combined effect of its covering wax and surface structure [84]. In fact, the lotus leaf presents a hierarchical surface structure that is composed of a dual-scale roughening at the micro-and nanoscale [84,85].…”

In fact, the lotus leaf presents a hierarchical surface structure that is composed of a dual-scale roughening at the micro-and nanoscale [84,85]. The process of mimicking the lotus leaf pattern on an artificial surface is a complex subject, because it involves precise control over surface microstructuring, while keeping the already obtained nanostructure on the surface.…”

Abstract:The current demand for fabricating optical and photonic devices displaying high performance, using low-cost and time-saving methods, prompts femtosecond (fs)-laser processing as a promising methodology. High and low repetition femtosecond lasers enable surface and/or bulk modification of distinct materials, which can be used for applications ranging from optical waveguides to superhydrophobic surfaces. Herein, some fundamental aspects of fs-laser processing of materials, as well as the basics of their most common experimental apparatuses, are introduced. A survey of results on polymer fs-laser processing, resulting in 3D waveguides, electroluminescent structures and active hybrid-microstructures for luminescence or biological microenvironments is presented. Similarly, results of fs-laser processing on glasses, gold and silicon to produce waveguides containing metallic nanoparticles, analytical chemical sensors and surface with modified features, respectively, are also described. The complexity of fs-laser micromachining involves precise control of material properties, pushing ultrafast laser processing as an advanced technique for micro/nano devices.

“…The obtained porous PSU membranes have a surface pattern that is a negative replica of the substrate. The method could also be used to prepare a surface with two-tier hierarchical structures that feature a super-hydrophobic property [52]. Recent research studies have focused on using a poly (dimethylsiloxane) (PDMS) replica mold as the substrate instead of the silicon wafer, and on using VIPS to precipitate the polymer solution instead of the wet method.…”

Morphology Control of Polysulfone Membranes in Filtration Processes: a Critical Review

et al. 2015

View full text Add to dashboard Cite

Polysulfone (PSU) membranes have been widely applied in microfiltration and ultrafiltration processes due to their excellent properties, such as chemical inertness across the entire pH range, compressive strength, and thermal stability. Despite these advantages, the application of PSU membranes in filtration processes has often been restricted due to their hydrophobic nature, which results in serious membrane fouling and a reduced permeate flux. Moreover, PSU membranes suffer from several disadvantages, including bulky structure, low binding force between fibers, and poor mechanical properties. The key factor in the development and application of polymeric membranes is the control of its polymeric morphology due to the significant influence of membrane morphology on the membrane performance. Effective techniques of controlling PSU membrane morphology are accessed, and the effects of the morphological control on mechanical properties, chemical stability, membrane performance, and membrane fouling are investigated. Findings from various individual studies were analyzed and discussed in order to provide a critical review of this subject. The results emphasized that the membrane pore size and surface porosity mostly governs PSU membrane morphology, which enhances membrane performance and reduces membrane fouling.
