“…Moving and scanning the femtosecond lasers across the object's surface introduces potential interference and diminishes the precision of the process. To circumvent errors caused by moving the laser beam, laser scanning is often achieved by controlling the movement of the movable platform [35,39,40]. Figure 1 is the schematic diagram of the laser fabrication system.…”

In recent years, superhydrophobic surfaces have attracted significant attention due to their promising applications, especially in ice prevention, reduction in air resistance, and self-cleaning. This study utilizes femtosecond laser processing technology to prepare different surface microstructures on polytetrafluoroethylene (PTFE) surfaces. Through experiments, it investigates the relationship between the solid–liquid contact ratio and surface hydrophobicity. The shape of water droplets on different microstructure surfaces is simulated using ANSYS, and the relationship between surface microstructures and hydrophobicity is explored in the theoretical model. A superhydrophobic surface with a contact angle of up to 166° was obtained by machining grooves with different spacings in polytetrafluoroethylene sheets with femtosecond laser technology. Due to the micro- and nanostructures on the surface, the oleophobicity of the processed oleophilic PTFE surface is enhanced.

“…Overall, the remarkable mechanical properties of PTFE membranes set them apart from other materials [28]. Their exceptional surface smoothness and outstanding tensile and compressive strength results in an extended operational life and signi cantly enhanced ltration e cacy [29]. Thus, PTFE membranes are the primary choice for most ltration applications.…”

Micropore Organic polymer membranes are indispensable for membrane filtration with well-established selectivity and permeability. Pressure-driven conditions in harsh acidic or alkaline environments can influence the mechanical properties of these materials. Diminished mechanical properties may include a shortened membrane lifespan, reduced filtration effectiveness, and increased filtration cost. Understanding of the intricate mechanisms influencing the mechanical properties of organic polymer membranes remains incomplete. In this study, a comprehensive investigation was carried out to characterize the mechanical properties of different membrane materials with similar and varying pore size parameters. The influence of different methods of membrane preparation on the mechanical properties of these materials was also explored. The Young’s modulus, tensile strength, and elongation at break values were compared for two organic polymer membranes: polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF). Results showed that the PTFE membranes demonstrated excellent Young’s modulus and tensile strength, while PVDF membranes excelled in elongation at break. Notably, the PTFE membrane with a pore size of 0.45 µm demonstrated a 9.2% higher tensile strength and an impressive 153.5% greater elongation at break compared to the PTFE membrane with a pore size of 3.0 µm. Organic filter membranes prepared by the phase transition method exhibited a more structured fiber filament arrangement, a smoother surface, reduced crack formation and extension, and a uniform pore size and distribution when compared to materials prepared using the tensile method. The results of this study expanded our understanding of the factors that can influence the mechanical properties of organic filtration membranes. These results provide the theoretical basis to explore novel strategies to improve the dependability and effectiveness of membrane separation technology and reduce associated expenses.
