Core@double-shell Structured High-k Nanocomposites for Dielectric and Electrical Energy Storage Applications: Experiment and Simulation
This work reports the advances of utilizing double-shell strategy to enhance electrical energy storage capability and suppress the dielectric loss of high-k polymer nanocomposites.Two types of core@double-shell structured matrix-free nanocomposites were prepared using an in situ atom transfer radical polymerization (ATRP) method to graft a block copolymer from BaTiO3 nanoparticle.The inner polymer shell is chosen to have either high dielectric constant or high electrical conductivity to increase the overall dielectric constant as well as energy storage of the composite.Finite element modeling was conducted to investigate the dielectric properties of the fabricated nanocomposites and it demonstrates that the nano-confinement of the more conductive phase in this multi-shell nanostructure is the key to achieve high dielectric constant and low loss.
