一种新的低成本，报道了一种绿色、可重复的乳酸杆菌辅助合成纳米钛酸钡的研究。用X射线和透射电子显微镜分析确定了纳米钛酸钡的形成。用Williamson-Hall方法估算了表观晶粒尺寸和晶格应变。发现了单个的纳米颗粒和一些尺寸为20-80 nm的聚集体。BaTiO_3/PVDF复合材料的介电性能有显著提高，而BaTiO_3/PVDF复合材料的介电性能有显著提高。纳米复合材料（C）2009 Elsevier B V.保留所有紧身衣
A new low-cost, green and reproducible Lactobacillus sp assisted biosynthesis of BaTiO3 nanoparticles is reported X-ray and transmission electron microscopy analyses are performed to ascertain the formation of BaTiO3 nanoparticles The apparent crystallite size and lattice strain are estimated from Williamson-Hall approach XRD analysis of the compound indicated the formation of a single-phase tetragonal structure Individual nanoparticles as well as a few aggregate having the size of 20-80 nm are found. A possible involved mechanism for the biosynthesis of nano-BaTiO3 has also been proposed in which ROS as well as partial pressure of gaseous hydrogen (rH(2)) of the culture solution seems to play an important role in the process Remarkable enhancement in dielectric properties was observed in BaTiO3/polyvinyliclene fluoride (PVDF) nanocomposite (C) 2009 Elsevier B V.
