The effects of electric field on the structure and optical properties of PbTiO3 nanocrystalline powders and epoxy resin composites were mainly studied.The structure, light scattering, UV absorption spectra and the second harmonic of samples prepared by polarized electric field in different curing processes were studied. The results show that the polarization electric field in different curing processes has a great influence on the structure and optical properties of nanocomposites. Finally, the mechanism of the electric field is discussed
