Abstract
The development of novel and stable metal–organic coordination polymer triboelectric materials is of great significance for the application of micro/nano power sources in self-powered systems. Here we report the example of a high-spintronic helical metal–organic chain (ZUT-9) by using ionic ligand. ZUT-9 has good chemical stability, functional tunability and excellent triboelectric output performance, which is superior to traditional polymer materials. By adjusting the type of metal and increasing the number of spinons in the metal center, the triboelectric behavior can be effectively improved. The good output performance makes ZUT-9 effective in preventing metal corrosion in cathodic protection system. Combined with theoretical calculation and magnetic behavior characterization, the results show that increasing the number of spinon can be an effective way to significantly enhance the electron delocalization effect and promote frictional power generation behavior. This study provides an idea for the research of helical metal–organic chain materials and will promote their application in self-powered electrochemical cathodic protection.
