摘　　要：通过棒式涂布的方法得到了厚度均匀的钛酸钡-环氧树脂复合厚膜。研究了环氧树脂的热固化性质及钛酸钡含量对复合材料的微观结构、剥离强度及介电性能的影响。结果表明:随着BaTiO3(BT)含量的增加,复合材料中的气孔不断增加,导致剥离强度在BT含量为40vol%时达到最高值后急剧下降。复合材料的介电常数及介电损耗随着BT含量的增加而不断增加。在BT含量一定时,复合厚膜的介电常数和介电损耗分别随着频率的增加而减小和增加。The thick film of BaTiO3-epoxy composite was fabricated over a large area with bar coating method. The curing behavior of the epoxy resin, the microstructure, peel strength and dielectric properties of BaTiO3-epoxy composite were investigated. The results show that when the loading of BT was 40 vol%, the peel strength of the composite achieved the maximum, and was rapidly reduced when the content of BT was further increased, which is caused by the increasing of air holes in the composite. The dielectric con...
