“…The scanning hatch in the longitudinal direction is 50 µm. Different from the iridescent structural colors obtained by other approaches, like laser interference lithography 24,26 or self-assembly, 27 all the surfaces exhibit the same color under any view angles. The results are consistent with that has been reported before.…”

“…22 Furthermore, surfaces with different wetting properties can be achieved by lasers in metals or polymers. [23][24][25] Roughness factor is the origin of the wetting behavior. However, the major disadvantage of the laser structuring is its low efficiency caused by direct-writing technique, in which a raster-scanning strategy is commonly applied.…”

Femtosecond laser processing is emerged as a promising tool to functionalize surfaces of various materials, including metals, semiconductors, and polymers. However, the productivity of this technique is limited by the low efficiency of laser raster scanning. Here we report a facile approach for efficiently producing large-area functional polymer surfaces, by which metal is firstly textured by a femtosecond laser, and the as-prepared hierarchical structures are subsequently transferred onto polydimethylsiloxane (PDMS) surfaces. Aluminum pieces covered by laser induced micro/nano-structures act as template masters and their performance of displaying diverse colors are investigated. Polymer replicas are endowed with tunable wetting properties, which are mainly attributed to the multi-scale surface structures. Furthermore, the surfaces are found to have extremely high adhesive force for water drops because of the high water penetration depth and the resultant high contact angle hysteresis. This characteristic facilitates many potential applications like loss-free tiny water droplets transportation. The reusability of metal master and easiness of soft lithography make it to be a very simple, fast and cost-efficient way for mass production of functional polymeric surfaces.

“…Laser interference demonstrates micro/nanostructures in air conditions by using a self-redistributed light intensity directly recorded in light-sensitive materials rather than using expensive masks [12]. Flexible structures, such as 1D gratings [14], 2D pillars/holes [15], and 3D crystal-like structures [16], have been produced.…”

Functional periodic structures have attracted significant interest due to their natural capabilities in regulating surface energy, surface effective refractive index, and diffraction. Several technologies are used for the fabrication of these functional structures. The laser interference technique in particular has received attention because of its simplicity, low cost, and high-efficiency fabrication of large-area, micro/nanometer-scale, and periodically patterned structures in air conditions. Here, we reviewed the work on laser interference fabrication of large-area functional periodic structures for antireflection, self-cleaning, and superhydrophobicity based on our past and current research. For the common cases, four-beam interference and multi-exposure of two-beam interference were emphasized for their setup, structure diversity, and various applications for antireflection, self-cleaning, and superhydrophobicity. The relations between multi-beam interference and multi-exposure of two-beam interference were compared theoretically and experimentally. Nanostructures as a template for growing nanocrystals were also shown to present future possible applications in surface chemical control. Perspectives on future directions and applications for laser interference were presented.

“…Inspired by nature, researchers have paid great attentions to the investigation of the wetting mechanisms and the fabrication of biological surfaces [4,5]. To date, a number of artificial biosurfaces have been successfully realized by various physical and chemical methods, including template methods, chemical vapor deposition, electrospinning, self-assembly, and laser microfabrication [6][7][8][9][10][11]. In recent years, rice leaf has attracted much attention because of its unique wettability.…”

In nature, rice leaves exhibit special anisotropic sliding capabilities. Although researchers have succeeded in fabricating artificial rice leaf structures and realizing the wettability function of the leaf surface, these methods used to date are complex and do not allow the fabrication of surfaces with large area. Herein, we adopted a simple technology -two steps soft transfer to fabricate biomimetic rice leaf. The fabricated surface well reproduced the structures of the rice leaf surface and exhibited a static superhydrophobic property similar to that of the real rice leaf surface. In terms of its dynamic wettability, it clearly exhibited an anisotropic sliding property. Systematic measurements showed that the sliding angles parallel and perpendicular with the vein direction were 25° and 40°, respectively. The method was simple and reliable, without the need for expensive instruments and complex technologies, which could be used for the rapid fabrication of large-area artificial rice leaf surfaces. We believe that the artificial rice leaf surface fabricated by this method has great potential applications in biomimetic functional surfaces, microfluidics, and so on.
