| 摘 要： | 基于钛酸钡和丁腈橡胶的高介电常数特性,研制了一种可用于内埋式电容器的钛酸钡/环氧复合材料.以丁腈橡胶作为添加剂,用共混法制备钛酸钡/环氧复合材料,探讨了钛酸钡和丁腈橡胶含量对复合材料介电常数、介电损耗因子、体积电阻率及击穿电压等介电性能的影响.实验结果表明,丁腈橡胶可以提高钛酸钡/环氧复合材料的介电常数.在钛酸钡体积分数为40%时,通过添加15%的丁腈橡胶,复合材料的介电常数可从25提高到41,体积电阻率达1011Ω·m,击穿电压达8 kV/mm,而介电损耗因子仍小于0.02.为工业化低成本生产内埋式电容器材料提供了一种新的方法.

| Abstract: | A novel BaTiO3/Epoxy composites used in embedded capacitor insulating material were prepared on basis of high dielectric constant properties of BaTiO3 and nitrile-butadiene rubber.The composite was prepared with BaTiO3,epoxy resin and nitrile-butadiene rubber.Influences of BaTiO3 and nitrile-butadiene rubber on dielectric properties of composite were discussed.Experimental results indicated that the adding of nitrile-butadiene rubber could improve the dielectric properties of BaTiO3/Epoxy composite,the diel... |
