1Surface functionalization of BiFeO3: A pathway for the enhancement of dielectric and electrical properties of poly(methyl methacrylate)-BiFe03 composite films显示文摘一部新奇二阶段的合成电影被作为陶器的 filler 作为聚合物矩阵和铋铁酸盐(BFO ) 扔 poly 采用的方法(甲基 methacrylate )(PMMA ) 的溶剂准备。BFO 的表面是由合适的 hydroxylating 代理人的 functionalized 激活他们的化学性质。合成电影的结构的分析证实由 functionalized BFO 组成的 composites (BFO -- 哦) 有弄歪的菱形的结构。词法分析显示出那 BFO -- 哦粒子同等地在聚合物矩阵上被散布。BFO 的 -OH 功能 -- 哦被 FTIR 证实。在到 1 MHz 的从 100 Hz 的一个频率范围的绝缘、电的研究揭示那 PMMA-(BFO -- 哦) composites 提高了绝缘的经常以及电的传导性,比未修改的 composites 的高得多。根据铁电体测量结果, hydroxylated 合成电影比未修改的的显示出优异铁电体行为,与残余的极化(2P 2.764 C/cm 2 的 r ) 。Mukesh Kumar MISHRA Srikanta MOHARANA Banarji BEHERA Ram Naresh MAHALING 2017Frontiers of Materials Science2017,11,1:2
2Enhanced dielectric and ferroelectric properties of surface hydroxylated Na_(0.5)Bi_(0.5)TiO_(3)(NBT)-poly(vinylidene fluoride)(PVDF)composites显示文摘The surface hydroxylation treatment has been carried out by using hydrogen peroxide(H_(2)O_(2))to modify the surface of Na_(0.5)Bi_(0.5)TiO_(3)(NBT)particles in a ferroelectric polymer(PVDF)via solution casting technique.The FTIR study confirms the presence of hydroxyl groups on the surface of NBT.The FE-SEM analysis reveals that h-NBT particles are dispersed homogeneously within the polymer matrix.The surface hydroxylation treatment plays an important role in high dielectric constant and also reduced loss by conducting the material surface withOH functional groups.The prepared composite with 40 wt.%of h-NBT showed enhanced dielectric constant(≈114),negligible loss(0.22)and high AC conductivity as compared to that of the unmodified NBT.Such significant enhancement in dielectric properties may be due to the strong interaction between h-NBT particles and PVDF matrix at the interface.The percolation theory is used to explain the dielectric properties of h-NBT-PVDF composite.Furthermore,the remnant polarization of the un-poled h-NBT-PVDF composites(2 Pr–1.19C/cm^(2) for 40 wt.%of h-NBT)is also improved.The present findings give an idea of high dielectric constant and relatively low loss composite materials as a promising candidate for electronic and energy storage devices.Srikanta Moharana Shraddhakara Sai Ram Naresh Mahaling 2018Journal of Advanced Dielectrics2018,8,3:1
