“…Polymer films deposited by electrospraying can range from spheres to fibers. 73 However, it is generally considered that fibers are produced during the electrospinning process, whereas beads are produced during the electrospraying process. 74 As shown in Figure 5, various lotus-leaf-like structures have been fabricated using electrospinning and electrospraying methods.…”

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.

“…In addition, SiO 2 is abundant, making the cost of production considerably low. Moreover, the chemistry of SiO 2 can be tailored easily using different polymers or metals . On the other hand, the hydrophobicity of SiO 2 are intrinsically poor; hence, its surface needs to be modified.…”

This paper reports a novel fluorinated micro‐nano hierarchical Pd‐decorated SiO2 structure (hereafter called Pd/SiO2), which was formed by the deposition of Pd nanoparticles (NPs) on SiO2 microspheres. The SiO2 layers with microscale roughness were fabricated by electrospraying a solution prepared using the sol‐gel process. Subsequently, the Pd NPs were deposited using an ultraviolet reduction process. The resulting surfaces exhibited a micro‐nano hierarchical morphology. After fluorination, the micro‐nano hierarchical surface exhibited outstanding water repellency with a water contact angle (WCA) of 170° and a sliding angle <5°, indicating excellent superhydrophobic properties. The layers exhibited good long‐term durability and excellent ultraviolet resistance. Interestingly, the surface was oleophilic (CA of oil ~10°). These results show the potential of employing superhydrophobic fluorinated Pd/SiO2 layers in smart devices, such as self‐cleanable surfaces and intelligent water/oil separation systems.

We fabricated novel superhydrophobic coatings based on SiO 2 nanoparticles combined with NH 2 -terminated silicone (SN 2 ) or SN 2 -modified polyurethane (SN 2 -prePU) by alternately spin-coating them onto glass slides. The final fabricated surface contained SN 2 /SiO 2 or SN 2 -prePU/SiO 2 bilayers. The conditions of spin-coating method were also explored. SN 2 -prePU with different SN 2 /prePU molar ratios were synthesized to study the influence of SN 2 ratio on the water contact angles of ultimate spin-coated surfaces. The surface was found to be tunable from hydrophobic to superhydrophobic by choosing SN 2 -prePU with different SN 2 / prePU molar ratios or SN 2 content. Water droplets easily rolled off on these superhydrophobic surfaces. Surfaces coated with SN 2 / SiO 2 bilayers showed better transparency, whereas surfaces coated with SN 2 -prePU(2 : 1)/SiO 2 bilayers exhibited better durability. Droplets of varied pH were prepared to test the anti-wettability of the coatings. Results showed that the as-coated surfaces had stable superhydrophobicity to droplets with pH values ranging from 1 to 14.
