In situ processing of electroceramic fine particles/polymer hybrids

Electroceramic fine particles/polymer hybrids have been receiving great attention in emerging areas. The conventional blending of fine particles into polymer or oligomer causes the particle agglomeration, leading to the degradation of properties. The newly developed method is based on the nucleation and growth control of crystalline oxide particles in organic matrix through the reaction control of a metallorganic precursor with a combination of the hydrolysis and polymerization below 100°C. The selection of reaction conditions does influence the size and crystallinity of ceramic particles in the organic matrix. The nano-sized magnetic particle/polymer hybrid exhibits the interesting feature of superparamagnetics and quantum size effect. The crystalline particles of BaTiO3/, and PbTiO3/polymer hybrids behave to be dielectric and show the typical electro-rheological behavior, which affords emerging areas.
