Liquid–solid
triboelectrification technology provides a new way to collect hydropower,
while the high cost, complexity, and easily damaged microstructures
of the triboelectric nanogenerator electrode materials highly limit
their practical applications. In this study, a new type of organic
coating triboelectric nanogenerator is fabricated using acrylate resin
as the friction layer material. To further improve the solid–liquid
triboelectrification performance and the hydrophobicity of the coating,
fluorine-containing materials were added to the acrylic resin. As
a non-microstructure-dependent film, its preparation process is simple
and large area prepared, which can be achieved by modifying some commonly
used anticorrosion and antifouling coatings in engineering. This packaged
organic coating triboelectric nanogenerator provides good stability
and high-output performance, which can easily light several commercial
light-emitting diodes (LEDs) on a model ship by collecting the wave
energy during the voyage. This new type of triboelectric nanogenerator
based on the coating material has the advantages of simple process,
low cost, and large-area preparation, which combines the performance
of the coating itself with the power generation function, and have
potential promising practical applications in ocean energy collection
and utilization, self-powered sensing, and other fields.
