Bentonite-derived monolithic materials with and without distributed nanoscale turbostratic carbon, obtained by hot-pressing organobentonite and bentonite particles, respectively, in the absence of an added binder, exhibit exceptionally high dielectric loss while the electrical conductivity is relatively low. The combination of high dielectric loss and relatively low conductivity has not been previously achieved. An additional advantage of these materials is their high-temperature ability. An… 

Structural characterizations and electrical conduction mechanism of CaBi2Nb2O9 single-phase nanocrystallites synthesized via sucrose-assisted sol–gel combustion method

A pure phase of nanocrystalline ferroelectric of calcium bismuth niobate (CaBi2Nb2O9, CBNO) has been synthesized via sucrose-assisted sol–gel combustion method. It was prepared using calcium nitrate,

Enhanced Dielectric and Mechanical Properties of Ternary Composites via Plasticizer-Induced Dense Interfaces

TLDR
A novel strategy of high-temperature plastification towards a polymeric matrix has been proposed to fabricate ternary nanocomposites with balanced dielectric and mechanical characteristics by the solution cast method in order to reduce costs and simplify steps during large-scale preparation.
