Progress in advanced electronics has initiated the investigation of new ways to develop and apply self‐powered smart devices. The concern for meteoric exhausting non‐renewable energy sources has spurred such endeavors. Even so, using external power sources like batteries is problematic due to limited capacity, maintenance inconvenience, replacement, and environmental hazards. Triboelectric nanogenerators (TENGs) capable of converting various forms of mechanical energies into electrical output are gaining popularity. The marine and coastal areas are abundant sources of salvable mechanical energy. TENGs can convert lower‐frequency, ununiform, multidirectional energies into usable electricity. This can solve the device‐powering problem and can generate diverse signals to act as monitoring or sensing platforms themselves. In this review, three main TENG‐based/TENG‐driven application themes are addressed, i.e., energy harvesting, marine environment monitoring, and self‐powered equipment for marine‐related activities. It attempts to emphasize that various design features of TENGs can influence output performance; TENGs can power devices and monitor ocean parameters; TENGs‐integrated modern IoT networking systems can transmit real‐time data. Overall, this review encompasses the fundamental working mechanisms, structure designs, and practical implementation scenarios of recently developed devices in diverse marine applications. Finally, the existing challenges and potential future directions for TENG‐based marine self‐powered electronic systems are discussed.

“…These nanomaterials enhance fabrics’ surface roughness through their inherent characteristics . Several hydrophobic reagents, like polysilane, cetyl alcohol, long-chain acid, hydrophobic polymers, and long-chain amine, are also used for fabric surface modification. − Berendjchi et al modified the cotton fabric using silica nanoparticles combined with ZnO nanorods and n -dodecyltrimethoxysilane (DTMS). The resulting cotton fabric showed antibacterial properties and superhydrophobicity.…”

Superhydrophobic textiles with multifunctional characteristics are highly desired and have attracted tremendous research attention. This research employs a simple dip-coating method to obtain a fluorine-free silica-based superhydrophobic and superoleophilic cotton fabric. Pristine cotton fabric is coated with SiO2 nanoparticles and octadecylamine. SiO2 nanoparticles are anchored on the cotton fabric to increase surface roughness, and octadecyl amine lowers the surface energy, turning the hydrophilic cotton fabric into superhydrophobic. The designed cotton fabric exhibits a water contact angle of 159° and a sliding angle of 7°. The prepared cotton fabric is characterized by attenuated total reflectance-fourier transform infrared spectroscopy, X-ray diffraction, atomic force microscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. In addition, the coated fabric reveals excellent features, including mechanical and chemical stability, superhydrophobicity, superoleophilicity, and the self-cleaning ability. SiO2 nanoparticles and octadecylamine-coated cotton fabric demonstrate exceptional oil–water separation and wastewater remediation performance by degrading the methylene blue solution up to 89% under visible light. The oil–water separation ability is tested against five different oils with more than 90% separation efficiency. This strategy has the advantages of low-cost precursors, a simple and scalable coating method, enhanced superhydrophobicity and superoleophilicity, self-cleaning ability, efficient oil–water separation, and exceptional wastewater remediation performance.
