“…The as-prepared PTFE film is obtained by a femtosecond laser line-by-line scanning process, and the experimental devices are schematically illustrated in Supporting Information (SI), Figure S1. Femtosecond laser processing has the advantages of no environmental pollution, simple preparation technology, high efficiency, and fast speed. − It can be applied to modify the microstructure and chemical compositions of a material, making it as a convenient technique for diverse applications. − The interaction between the laser beam and the sample readily changes the pristine flat hydrophobic PTFE surface into a hierarchical porous superhydrophobic PTFE surface (Figure c).…”

Passive cooling materials that spontaneously cool an object are promising choices for mitigating the global energy crisis. However, these cooling effects are usually weakened or lost when dust contaminates the surface structure, greatly restricting their applications. In this work, a robust hierarchical porous polytetrafluoroethylene (PTFE) film with coral-like micro/ nanostructures is generated by a facile and efficient femtosecond laser ablation technique. Owing to its unique micro/nanostructures, the as-prepared surface exhibits an outstanding self-cleaning function for various liquids with ultralow adhesion. This selfcleaning characteristic enhances the durability of its passive cooling effect. It is demonstrated that the titanium (Ti) sheet covered with laser-ablated PTFE film can realize a maximum temperature decrease of 4 and 10 °C compared to the Ti sheet covered with pristine PTFE film and uncovered, respectively. This study reveals that femtosecond laser micromachining is a facile and feasible avenue to produce robust self-cleaning passive cooling devices.

“…This process offers potential in the mass production of superhydrophobic coatings. In addition, the antifouling and drag reduction characteristics of hydrophobic coatings make them widely used in marine vehicles [53,54]. By suspension flame spraying, Zhai et al [55] deposited perfluoroalkoxy (PFA)/nano-silver (Ag) hydrophobic coatings on aluminum substrates using PFA/AgNO 3 suspension.…”

Inspired by the micro-nano structure on the surface of biological materials or living organisms, micro-nano structure has been widely investigated in the field of functional coatings. Due to its large specific surface area, porosity, and dual-scale structure, it has recently attracted special attention. The typical fabrication processes of micro-nano structured coatings include sol-gel, hydrothermal synthesis, chemical vapor deposition, etc. This paper presents the main features of a recent deposition and synthesis technique, liquid plasma spraying (LPS). LPS is an important technical improvement of atmospheric plasma spraying. Compared with atmospheric plasma spraying, LPS is more suitable for preparing functional coatings with micro-nano structure. Micro-nano structured coatings are mainly classified into hierarchical-structure and binary-structure. The present study reviews the preparation technology, structural characteristics, functional properties, and potential applications of LPS coatings with a micro-nano structure. The micro-nano structured coatings obtained through tailoring the structure will present excellent performances.

“…Femtosecond laser ablation, as a novel physical technique, has been widely used to precisely control the surface patterns and effectively change the physical and chemical properties of the material interface. [ 23–27 ] In this work, we report a femtosecond laser direct writing method to fabricate superhydrophilic micro/nanostructured nickel foam for high‐performance glucose sensor. Taking the advantage of its superhydrophilic property, the obtained electrochemical results exhibit the sensitivity of 13.822 mA cm –2 mM –1 and detection limits of 1.9 × 10 −6 m , which is much superior to the performance from other nickel‐based materials.…”

Porous materials with micro/nanostructures have demonstrated intriguing performance in glucose sensor. However, current methods have been limited to complex, time‐consuming, and toxic manufacturing process or unsatisfactory performance, which hugely restricts its practical applications. Herein, for the first time, a fast, simple, and nonpollution femtosecond laser direct writing technology is proposed to fabricate high‐performance glucose sensor. The as‐prepared nickel foam exhibits micro/nanostructures with superhydrophilic property, resulting in superior electrochemical sensing performance toward glucose. The sensitivity is determined to be 13.822 mA cm−2 mM−1 with the detection limit of 1.9 × 10−6 m, outperforming the results from the most, previously reported works. Meanwhile, the excellent selectivity for glucose detection is also demonstrated in the presence of interferences. This work is an attractive candidate for fast fabrication and designing of high‐performance glucose sensor.
