The decay of CE charges (induced by contacting with the DI water at room temperature) on a MgO, b Si3N4, c Ta2O5, d HfO2, e Al2O3, and f AlN surfaces at 433 K, and the amount of the electron transfer and the ion transfer in the CE between the DI water and different insulators. g The relation between the electron transfer to the ion transfer ratio and the DI water contact angle (WCA) of the materials. h The schematic of WCA effects on the ion transfer and electron transfer in liquid–solid CE. γL, γS, and γL−S denote the liquid–gas interfacial tension, solid–gas interfacial tension and liquid–solid interfacial tension, respectively. (Error bar are defined as s. d.).
