Dielectric properties of nano-(MgO–Gd2O3) Co-doped alumina for high voltage insulators

Super Electrical Insulating Materials Based on Honeycomb‐Inspired Nanostructure: High Electrical Strength and Low Permittivity and Dielectric Loss

“…Substituting Equations ( 13) and ( 14) into Equation (18) gives the head scale of the electron avalanche as…”

“…This fails to fully utilize the potential of nanostructures and results in limited increases in the breakdown field strength (generally below 30%) and high dielectric loss. [15][16][17][18][19][20] This is unacceptable in power equipment, especially for power frequency operations.Recent studies have indicated that the macroscopic properties of materials are closely related to their microstructure. [21][22][23][24][25][26] Inspired by the pore structures of honeycombs in nature, we propose constructing nanopore structures to divide traditional insulating materials into nanosized microunits to fully develop the effects of nanostructures.…”
