Tailoring micro/nanostructured porous polytetrafluoroethylene surfaces for dual-reversible transition of wettability and transmittance

Kai Yin et al.

Summary: In this study, a textured polytetrafluoroethylene (PTFE) film with hierarchical porous micro/nanostructures was fabricated using femtosecond laser technology. The film exhibited both superhydrophobicity and opacity, and its wettability and optical transmittance could be simultaneously controlled. By prewetting and drying the film, it could switch between superhydrophilicity and superhydrophobicity. The study demonstrated the potential applications of this smart surface in light pass/block controlling, anti-fogging, and cooling.

Femtosecond Laser Thermal Accumulation-Triggered Micro-/Nanostructures with Patternable and Controllable Wettability Towards Liquid Manipulating

Kai Yin et al.

Summary: A method for fabricating liquid manipulating surfaces with patternable and controllable wettability on Polyimide film using femtosecond laser thermal accumulation engineering is proposed. The wettability of the film can be controlled from superhydrophilicity to superhydrophobicity through adjusting the local thermal accumulation. Three different surfaces with patternable and heterogeneous wettability were constructed and various applications were achieved.

Femtosecond-laser sharp shaping of millimeter-scale geometries with vertical sidewalls

Qiuchi Zhu et al.

Summary: A novel fs laser sharp shaping approach was developed to address key challenges in macroscale machining, achieving sharp edges and vertical sidewalls through parameter compensation strategy. The method provides a versatile solution for geometries of different shapes and dimensions, enabling dimensional precisions below 10 μm and surface roughness below 1 μm in general manufacturing applications.

Solar-driven thermal-wind synergistic effect on laser-textured superhydrophilic copper foam architectures for ultrahigh efficient vapor generation

Kai Yin et al.

Summary: Solar-driven vapor generation is enhanced by combining thermal and wind effects on a superhydrophilic copper foam surface, increasing the rate of water evaporation. The treated surface absorbs significant solar power which can be converted into heat for steam generation, while a pre-wetted sponge minimizes heat loss and helps maintain high evaporation rates.
