“…Furthermore, according to the anisotropy of the WCA, the surface wettability can be either isotropic or anisotropic surface wettability (ASW). Various surface wettability phenomena occur in nature, such as the isotropic superhydrophobicity of lotus leaves ( Zhang et al, 2009 ) and rose petals ( Feng et al, 2008 ), isotropic superhydrophilicity of snail shells ( Jiang et al, 2015 ), anisotropic superhydrophobicity of rice leaves and butterfly wings, and slippery surface wettability of ice ( Rosenberg, 2005 ), pitcher plants ( Bohn and Federle, 2004 ), and loach skin ( Seo et al, 2021 ). Inspired by nature, biomimetic materials with special surface wettability characteristics have been designed and fabricated by controlling the surface morphology and chemical composition following the principles of Young’s equation ( Young, 1805 ), and the Wenzel ( Wenzel, 1936 ) and Cassie–Baxter models ( Cassie and Baxter, 1944 ).…”

Porous polydimethylsiloxane (PDMS) films with special surface wettability have potential applications in the biomedical, environmental, and structural mechanical fields. However, preparing porous PDMS films with a regular surface pattern using conventional methods, such as chemical foaming or physical pore formation, is challenging. In this study, porous PDMS films with a regular surface pattern are designed and prepared using 3D printing to ensure the formation of controllable and regular physical structures. First, the effect of the surface wettability of glass substrates with different surface energies (commercial hydrophilic glass and hydrophobic glass (F-glass) obtained by treating regular glass with 1H,1H,2H,2H-perfluorooctyl-trichlorosilane) on the structural characteristics of the 3D printed PDMS filaments is investigated systematically. Additionally, the effect of the printing speed and the surface wettability of the glass substrate on the PDMS filament morphology is investigated synchronously. Next, using the F-glass substrate and an optimized printing speed, the effects of the number of printed layers on both the morphologies of the individual PDMS filaments and porous PDMS films, and the surface wettability of the films are studied. This study reveals that regularly patterned porous PDMS films with distinct structural designs but the same controllable surface wettability, such as anisotropic surface wettability and superhydrophobicity, can be easily fabricated through 3D printing. This study provides a new method for fabricating porous PDMS films with a specific surface wettability, which can potentially expand the application of porous PDMS films.

“…Due to the exible deformation of loach's body, tiny scale distribution on the body surface, and the mucus retained on the scales, the DR performance of the loach is maximized. 25,26 Although the microstructure of the loach body surface triggers inspiration for the design of the bionic surface and has achieved some positive results on DR and anti-fouling, [27][28][29] further in-depth analysis on DR mechanisms is required and preparation of large-area microstructure for application is a challenge as well. In this study, the scale morphology of the loach was described, and the most appropriate structural characteristic parameters were selected.…”

Fish is a common and widely distributed creature. Its skin has a unique physiological structure and plays an important role in many fields. Fish skin also has important potential value for bionics research. This study aims to provide a method and a reliable data for the study of bionics. A method of measuring the mechanical properties of fish skin samples using a binocular stereo digital image correlation (DIC) system combined with a synchronous tensile testing machine was proposed. The mechanical properties (e.g., elastic modulus E and strain) of grass fish skin samples (GFSA) were tested in hydrophilic and dry states. A dual-frequency laser interferometer was used to calibrate the tensile testing machine synchronously, and the feasibility and strain accuracy of DIC in GFSA measurement were verified by finite element method (FEM). The results show differences in the mechanical properties of GFSA between different individuals, different parts, and different states. Under the same stress, the head was easy to deform, and the strain was the largest, and E was the smallest. The tail result was the opposite of the head result.
