Preparation, Properties and Application Prospects of Ferroelectic Nanomaterials
铁电纳米材料的制备、性能和应用前景

The preparation, structure and properties of ferroelectric nanometer sized powders, nanocomposites, and nanoceramics were introduced. The change of structure and properties caused by the reduction of particle size and pertinent mechanisms were discussed. Transparent nanocomposites were expected to be applied as the optical memories, optical computer, etc devices, while the nanoceramics can be widely used to improve the characteristic parameters of current capacitors due to the greatly enhanced dielectric permittivity, breakdown voltage, ageing-resistivity, mechanical strength, etc. Better quality of devices will be obtained by using the nanosized powders.
