Triboelectric Nanogenerators: Triboelectric Series of 2D Layered Materials (Adv. Mater. 39/2018)

In article number 1801210, Sang-Woo Kim, Hyeon-Jin Shin, and co-workers report an investigation on the triboelectric charging behaviors of various two-dimensional (2D) materials, including MoS2, MoSe2, WS2, WSe2, graphene, and graphene oxide by using the concept of the triboelectric nanogenerator (TENG). The relative charging polarities of the 2D materials against materials in the conventional triboelectric series are observed by analyzing the output signals obtained from TENGs of various combinations.
