“…In addition, inversion of the boiling curve (Jaikumar and Kandlikar, 2017) has been achieved by controlling the behavior of boiling bubbles by separating nucleating regions and the paths of liquid supply (Kandlikar, 2017). Various methods have been used to fabricate localized nanostructures or wettability patterns, including micro-electro mechanical systems (MEMS) techniques (Chu et al, 2012), laser surface treatment (Kumar et al, 2020), and chemical etching (Kim et al, 2011) and plating (Sinha-Ray et al, 2011). However, the equipment required for MEMS and laser systems is expensive, and the environmental impact and disposal costs of the chemicals used in these methods are high.…”

“…Although boiling heat transfer is one of the most intense heat transfer mechanisms, researchers in this field have extensively investigated numerous types of methods in the last few decades [8,9] to further improve the boiling performance. Studies range from enhancements based on boiling fluid modification, [9,10] such as with the addition of nanoparticles (i.e., nanofluids) [11,12] or with mixtures of different surface tensions, [13,14] to studies focusing on surface modification, [15,16] with an emphasis on changing the surface topography [17,18] and morphology [19,20] alongside with its wetting behavior. [21,22] In recent years, various technologies have been explored to tailor the surface topography and morphology to improve boiling performance.…”

The rapid advancement of engineering systems has spurred the search for innovative thermal management solutions. Boiling, as a phase‐change heat transfer method, has shown promise in heat dissipation, but non‐functionalized surfaces struggle with increasing cooling demands. To improve heat dissipation efficiency across different heat loads, functionalized surfaces with tailored wettability have been proposed. Separately, superhydrophilic and superhydrophobic surfaces each offer benefits and drawbacks in boiling applications but combining them on a single “biphilic” surface simultaneously harnesses their advantages. In this study, laser‐functionalized copper surfaces with spatially tailored wettability are developed by combining two‐step laser texturing with a self‐assembled monolayer coating, while focus is placed on the impact of the size and pitch of superhydrophobic spots. The developed functionalized surfaces exhibit exceptional boiling performance with heat transfer coefficients up to 299 kW m−2 K−1, a 434% enhancement over untreated surfaces. Optimal ratios of superhydrophilic and superhydrophobic areas and optimal spot pitch are identified. Additionally, varying behavior at different heat flux levels is observed, emphasizing the importance of considering thermal loads when determining the optimal surface pattern. This advancement in performance, along with the rapid and cost‐effective functionalization process, represents a significant breakthrough for enhanced thermal management applications.

“…Laser processing ablation obtains the desired surface features on the metal; such modified surfaces can be both beneficial and durable in phase-change heat transfer applications. Surface modification by ultra-short pulse lasers alters the heat transfer performances of the boiling system [111]. Since the LIPSSs can significantly increase the absorption rate of the surface, they will simultaneously lead to an increase in thermal radiation.…”

As a laser technology, the femtosecond laser is used in biomedical fields due to its excellent performance—its ultrashort pulses, high instantaneous power, and high precision. As a surface treatment process, the femtosecond laser can prepare different shapes on metal surfaces to enhance the material’s properties, such as its wear resistance, wetting, biocompatibility, etc. Laser-induced periodic surface structures (LIPSSs) are a common phenomenon that can be observed on almost any material after irradiation by a linearly polarized laser. In this paper, the current research state of LIPSSs in the field of biomedicine is reviewed. The influence of laser parameters (such as laser energy, pulse number, polarization state, and pulse duration) on the generation of LIPSSs is discussed. In this paper, the applications of LIPSSs by femtosecond laser modification for various purposes, such as in functional surfaces, the control of surface wettability, the surface colonization of cells, and the improvement of tribological properties of surfaces, are reviewed.
