Introducing high-permittivity nano-fillers into a dielectric polymer is a practical way to enhance the permittivity of nanocomposite dielectrics. However, this normally leads to a decrease in the breakdown strength, which has limited the development of electrostatic capacitors. In this work, silica (SiO2) coating and polydopamine (PDA)
3.1.1. Template-directed synthesis. Sacrificial template-assisted synthesis is a crucial technique for crafting yolk and core–shell structures, enabling meticulous control of their shape, composition, and properties. 79 This method relies on sacrificial materials, which are strategically eliminated after the synthesis to form void spaces or distinct shell layers.
