1 Introduction Over the past decade, research on small-scale energy harvesting and utilization has gained considerable significance.[1] For instance, triboelectric energy in everyday life can be harvested and utilized for various purposes.[2] Since the Wang group developed triboelectric nanogenerators (TENGs),[3] extensive research has focused on fabricating new devices.[4] In addition, to improve the efficiency of TENGs, extensive studies have been conducted on triboelectric materials.[5] As...

A very small amount (0.1 wt%) of Co(OH)2 nanoplates enhances triboelectric performance of polymers Hexagonal Co(OH)2 nanoplates with a diameter of 1.28 ± 0.08 m and a thickness of 52 ± 14 nm were prepared, showing facile generation of static electricity in a plastic container. Based on this observation, Co(OH)2 nanoplates were incorporated into polymer matrixes such as polyvinylpyrrolidone (PVP) and polyurethane (PU).
