Functional sponge-based triboelectric nanogenerators with energy
Here, an advanced triboelectric nanogenerator (TENG) with mechanical/magnetic energy harvesting and smart oil–water separating performance was fabricated by assembling a magnetic sponge with a conductive polymer film. The sponge was facilely prepared by dispersing carbonyl iron into Ecoflex using a sugar sacial templating technique.
