Abstract

Grafting functional groups allows precise control over triboelectric properties, enhancing triboelectric nanogenerator (TENG) performance. In this study, we improved TENG efficiency using Isochrysis galbana particles (IGPs) with hydrophilic and hydrophobic modifications for mechanical and blue energy harvesting. For hydrophilic modification, hydroxyl-rich IGPs were treated with dopamine to form HIGDAPs, which were then combined with polyvinyl butyral (PVB) to fabricate HIGDAPs/PVB nanofibers. This TENG achieved an output of 800 V and 0.4 μA/cm², sufficient to power 500 LEDs, and showed excellent biocompatibility for wearable sensors. For hydrophobic modification, IGPs were esterified with oleoyl chloride, and HIGOEPs were sprayed onto PET fabric to fabricate a waterproof surface for blue energy harvesting. Optimal performance was achieved at a 30° angle, generating 1 V and 1.9 μA due to a maximized contact area of 5.48 mm².

期刊介绍： Nano Energy is a multidisciplinary, rapid-publication forum of original peer-reviewed contributions on the science and engineering of nanomaterials and nanodevices used in all forms of energy harvesting, conversion, storage, utilization and policy. Through its mixture of articles, reviews, communications, research news, and information on key developments, Nano Energy provides a comprehensive coverage of this exciting and dynamic field which joins nanoscience and nanotechnology with energy science. The journal is relevant to all those who are interested in nanomaterials solutions to the energy problem. Nano Energy publishes original experimental and theoretical research on all aspects of energy-related research which utilizes nanomaterials and nanotechnology. Manuscripts of four types are considered: review articles which inform readers of the latest research and advances in energy science; rapid communications which feature exciting research breakthroughs in the field; full-length articles which report comprehensive research developments; and news and opinions which comment on topical issues or express views on the developments in related fields.
