Abstract Inspired by nature's ability to master materials for performance and sustainability, biomimicry has enabled the creation of bioinspired structural color, superadhesion, hydrophobicity hydrophilicity, among many others. This review summarizes emerging trends in novel sustainable fluorocarbon‐free designs creating superhydrophobic superoleophobic surfaces. It discusses methods, challenges, future directions, alongside impact computational modeling artificial intelligence accelerating experimental development more surface materials. While significant progress is made materials, surfaces remain a challenge. However, bioinspiration techniques supported platforms are paving way new renewable biodegradable repellent that meet environmental standards without sacrificing performance. Nevertheless, despite concerns, policies, several still continue apply fluorination other environmentally harmful achieve required standard repellency. As discussed this critical review, paradigm integrates advanced characterization, nanotechnology, additive manufacturing, modeling, coming, generate with tailored superhydrophobicity superoleophobicity while adhering standards.

ABSTRACT The development of permanent superhydrophobic surfaces has attracted significant attention due to their usage in many applications, particularly environmental and biomedical remediations. Among the various fabrication techniques, electrospinning emerged as an advantageous flexible method for fabricating nanofibers with tailored surface characteristics. In this study, we explore enhancement properties by incorporating Teflon particles into matrices polystyrene (PS) polyvinyl chloride (PVC) through process. Electrospinning was employed fabricate three‐dimensional (3D) structured without highly hydrophobic average particle size 180 nm. Following these nanofibers, a series heat treatments were applied at temperatures (0°C, 50°C, 75°C, 100°C, 125°C) different durations (30 min, 1 h, 2 4 h) improve further. hydrophobicity assessed water contact angle (WCA) measurements, which confirmed that all exhibited behavior. addition particles, combined treatment, significantly enhanced resulting WCA values 155.75° PS 151.62° PVC thereby categorizing them having properties. Further characterization conducted using scanning electron microscopy (SEM) Fourier‐transform infrared (FTIR) spectroscopy analyze morphology chemical compositions. These analyses indicated consistently fell within submicron nanoscale range, uniform distribution observed across nanofiber surfaces. resultant fiber diameters range 400 nm μm, while ranged from 200 600 Collectively, results suggest fabricated 3D are viable candidates health remediations energy mitigations.
