摘要

摘要通过在滚屏己酸盐(HNB)纳米片上控制捕获纳米颗粒(NPs)，制备了钛酸钡(BaTiO3)豆荚纳米复合材料。BaTiO3 NPs和质子交换的己酸钾在甲苯中220°C溶剂热处理6小时，得到了限制在多壁HNB纳米卷内的线性NP链。该方法制备的纳米脚平均填充分数大于70%。纳米组分的可控引入以及油胺和油酸表面活性剂的组合对这些反应的成功至关重要。形成BaTiO3@HNB的能力大大增加了通过控制NP捕获可获得的重要豆荚复合材料的数量。

Directed assembly of barium titanate nanopeapods via solvothermal processing with a mixed surfactant system

Abstract Barium titanate (BaTiO3) peapod nanocomposites were prepared by the controlled capture of nanoparticles (NPs) in scrolling hexaniobate (HNB) nanosheets. BaTiO3 NPs and proton-exchanged potassium hexaniobate were treated solvothermally at 220 °C for 6 h in toluene to produce linear NP chains confined within multiwalled HNB nanoscrolls. This method consistently produced nanopeapods with average filling fractions greater than 70%. The controlled introduction of nanocomponents along with a combination of oleylamine and oleic acid surfactants was critical to the success of these reactions. The ability to form BaTiO3@HNB significantly expands the number of important peapod composites accessible by the controlled NP capture.

期刊介绍： Journal of Experimental Nanoscience, an international and multidisciplinary journal, provides a showcase for advances in the experimental sciences underlying nanotechnology and nanomaterials. The journal exists to bring together the most significant papers making original contributions to nanoscience in a range of fields including biology and biochemistry, physics, chemistry, chemical, electrical and mechanical engineering, materials, pharmaceuticals and medicine. The aim is to provide a forum in which cross fertilization between application areas, methodologies, disciplines, as well as academic and industrial researchers can take place and new developments can be encouraged.
