| Abstract Scope |
Using cold sintering, it has been able to demonstrate that novel phases, such as polymers, can be readily incorporated into the grain boundaries of a ceramic material. Typically, grain boundaries do not have ferroelectric activity; they are more likely to be inactive amorphous dielectric glass phases. Current research aims to consider dielectric oxide grains and a new type of ferroelectric intergranular phase based on organic/inorganic hybrid perovskite structures, and/or ionic ferroelectric polymers that are both ferroelectric active. By analyzing the microstructure of the ceramic-ferroelectric polymer composite, and characterizing its electrical and thermal properties, new families of ferroelectrics could be considered for new application opportunities in energy harvesting, capacitors, and actuators on flexible substrates. These materials and low temperature processes permit the possibility of hierarchical organic-inorganic functional composites ranging from the molecular level to the nanostructured phase distributions in the grain boundary phases. |
