Abstract
The invention relates to an energy harvesting and self-cleaning system based on graphene aerogels and its preparation method, which a layer of metal collector is sputtered on both sides of the freeze-dried graphene aerogel by magnetron sputtering; the graphene aerogel with collector is fixed on the side and bottom of the substrate in series and/or parallel connection, and then is put into the electrolyte to get the target system. The system provides a new idea for mechanical energy harvesting. Firstly introduced aerogels into the field of mechanical energy harvesting. In addition, the system can not only collect mechanical energy, but also absorb oil and other impurities in the ocean, playing the role of ocean cleaning. The energy collection system formed by single aerogel can produce ˜220 mV open circuit voltage in Sodium Chloride Solution or organic electrolyte, and generate 2 W/kg power density.
