“…Thus, Li et al found an important increase of hydrophobicity when combining in a mat polystyrene and nylon6 electrospun fibers with mean diameters quite different from each other [34]. The combination of thin and thick fibers mimics the superhydrophobic surfaces of living organisms such as lotus leaf [25]. Simultaneous contributions of chemical and topographical cues to hydrophobicity can be obtained by coating electrospun fibers with more hydrophobic polymers [35].…”

Royal Society of ChemistryAreias, A.; Ribeiro, C.; Sencadas, V.; Garcia Giralt, N.; Diez Perez, A.; Gómez Ribelles, JL.; Lanceros Mendez, S. (2012). Influence of crystallinity and fiber orientation on hydrophobicity and biological response of poly(L-lactide) electrospun mats. Soft Matter. 8 (21) AbstractPoly(L-lactide) electrospun mates have been produced with random and aligned fiber orientation and degrees of crystallinity from 0 up to nearly 50%. These two factors, fiber alignment and degree of crystallinity strongly affect the hydrophobicity of the samples, being this larger for the aligned fiber mats and for the fibers with higher degree of crystallinity. Whereas the first effect can be associated to a decrease in the degree of porosity the second should be related to variations in the fiber roughness at nanometric scale and an increase in fiber stiffness. Proliferation of human chondrocytes cultured in monolayer on these substrates is similar in both aligned and non-aligned amorphous mats. Crystallization of the aligned mats, on the other hand, nearly suppresses proliferation and the cells produce higher amounts of aggrecan, characteristic of the extracellular matrix of hyaline cartilage.

“…When water flows over such a surface, a reduction in skin friction is observed [20]. Two recent reviews [68,69] discussed several techniques to develop superhydrophobic and oleophobic fibrous surfaces using electrospinning methods. Random, aligned, and spider-web-like nanofiber/net structures can be produced.…”

Abstract:We review recent developments in nature-inspired superhydrophobic and omniphobic surfaces. Water droplets beading on a surface at significantly high static contact angles and low contact-angle hystereses characterize superhydrophobicity. Microscopically, rough hydrophobic surfaces could entrap air in their pores resulting in a portion of a submerged surface with air-water interface, which is responsible for the slip effect. Suberhydrophobicity enhances the mobility of droplets on lotus leaves for self-cleaning purposes, so-called lotus effect. Amongst other applications, superhydrophobicity could be used to design slippery surfaces with minimal skin-friction drag for energy conservation. Another kind of slippery coatings is the recently invented slippery liquid-infused porous surfaces (SLIPS), which are one type of omniphobic surfaces. Certain plants such as the carnivorous Nepenthes pitcher inspired SLIPS. Their interior surfaces have microstructural roughness, which can lock in place an infused lubricating liquid. The lubricant is then utilized as a repellent surface for other liquids such as water, blood, crude oil, and alcohol. In this review, we discuss the concepts of both lotus effect and Nepenthes slippery mechanism. We then present a review of recent advances in manufacturing polymeric and non-polymeric slippery surfaces with ordered and disordered micro/nanostructures. Furthermore, we discuss the performance and longevity of such surfaces. Techniques used to characterize the surfaces are also detailed. We conclude the article with an overview of the latest advances in characterizing and using slippery surfaces for different applications.

“…71 For the formation of uniform fibers, the molecular weight of the polymer and the concentration of the solution should be properly controlled. 72 On the other hand, the electrospraying technique is not necessarily restricted to fibers. Polymer films deposited by electrospraying can range from spheres to fibers.…”

Various biomaterials have been widely used for biomedical applications, including bio-organs, medical devices, and clinical devices like vessel, blood pumps, artificial kidneys and hearts, even in contact with blood. The issue of blood compatibility has been studied intensively to prevent negative effects such as thrombosis due to the implanted devices. The use of lotus-leaf-like structured surfaces has been extended to an increasing number of applications such as contamination prevention and anticorrosion applications. Various methods such as template, sol-gel transition, layer-bylayer, and other methods, developed for the fabrication of lotus-leaf-like surfaces have been reported for major industrial applications. Recently, the non-wettable character of these surfaces has been shown to be useful for biomedical applications ranging from blood-vessel replacement to antibacterial surface treatment. In this review, we provide a summary of current and future research efforts and opportunities in the development and medical applications of lotus-leaf-like structure surfaces.
