摘要
制备了以PVDF为母体的TGS、BaTiO3、LiNbO3及PZT的O—3型复合材料.研究了这些材料的长时间极化弛豫,发现存在三种带有不同弛豫时间的驰豫机构,这些机构分别由晶粒、母体及晶粒边界产生,晶粒边界产生的极化较稳定.
The O-3 type composites of TGS, BaTiO3, PZT and LiNbO3 based on PVDF were prepared.The long term polarization relaxation in these composites was studied. It indicates that there arethree mechanisms with different relaxation time. These mechanisms result from crystalline grainsof the crystal or ceramics, matrix and grain boundaries. A stable polarization results from thegrain boundaries.
