Energy conservation and environmental protection have gradually gained popularity, and the unsustainable use of solar energy and wind energy resources has become a major objective factor restricting the development of wind energy equipment and solar energy equipment.

Recently, a wave power generation product developed by scientists at the Georgia Institute of Technology in the United States has successfully avoided the issue of sustainability. The nano-friction generator of ocean wave power generation is simple in structure, cheap and easy to use, and can work continuously around the clock.
As a renewable energy source, the biggest drawback of solar and wind energy is unsustainability – sunny days and windy days are not always met. In this regard, waves have an unparalleled advantage. According to a report by the physicist organization network on October 15, a use was developed. Researchers say the generator-related paper was published in the journal Applied Chemistry.
The frictional power generation effect is a phenomenon in which two materials contact and separate to generate electric charges. Wang Zhonglin, a team at the Georgia Institute of Technology in charge of the research, has previously developed a solid-state friction generator that can charge mobile phone "target=_blank" batteries. The problem with the new research is how to make friction Is electricity generated in a humid, seawater environment?
Researchers have found that frictional power generation is not limited to solids, it is also present in liquid environments. The only requirement is that the specific electron energy levels of the two substances are close enough. For water, all it needs is a suitable "camper." Through experiments, they found a special plastic or can do this.
As a prototype, the researchers made an insulated plastic container. This container has a lid and a bottom on which electrodes made of copper sheets are mounted. Their system succeeded because the inside of the lid was coated with a layer of nano-scale, micro-pyramid polydimethylsiloxane (PDMS). The container is filled with deionized water. When the lid is lowered, these micro-pyramids come into contact with water, and a batch of polydimethylsiloxane atoms are ionized, resulting in a negative charge; at the same time, a positive charge is generated on the water surface. A complete triboelectric power generation process is completed when the polydimethylsiloxane layer leaves the water to charge.
The principle is to utilize the potential difference between polydimethylsiloxane and water. The reason for choosing polydimethylsiloxane is that its excellent hydrophobicity reduces the adhesion of water, and the unique pyramid shape makes it easier for water to fall off.
When placed in seawater, the device rises and falls periodically with the waves, the electrodes connected to the rectifier and capacitor, and the resulting DC power can illuminate 60 ç› LEDs. The researchers say the device has a wide range of applications and can be used as a temperature sensor due to temperature sensitivity; it can also provide more imagination for the design of biomolecular sensors and chemical sensors, as other sensors are attached to it. space.
