Effects of Sub-Micro Sized BaTiO3 Blocking Particles and Ag-Deposited Nano-Sized BaTiO3 Hybrid Particles on Dielectric Properties of Poly(vinylidene-fluoride) Polymer

This work provided an alternative route to balance the significantly increased dielectric permittivity (ε′) and effectively retained tanδ using an effective two-step concept. Ag-deposited nano-sized BaTiO3 (Ag-nBT) hybrid particle was used as the first fille...
