摘要
利用简易的“一锅法”制备了正丁硫醇修饰的MoS2纳米片(MoS2-C4), 并对其结构、组分、形貌及电双稳性能进行了研究。正丁硫醇在反应过程中既作为硫源, 又作为表面活性剂。X射线衍射(XRD)测试表明制备的样品为六方晶系的MoS2。从透射电镜(TEM)和原子力显微镜(AFM)可以看出样品的形貌为片状, 较大的纳米片是由较小的纳米片自组装而成。测试了样品的吸收光谱, 由吸收峰的位置证明了合成的样品为2H-MoS2纳米片。利用旋涂法将所制备的纳米片与聚乙烯基咔唑(PVK)的混合物制备了电双稳器件, 通过电流-电压(I-V)测试证明了该器件具有很好的电双稳性能。
Abstract
n-butyl mercaptan modified molybdenum disulfide nanosheets (MoS2-C4) are synthesized by simple one-pot method. The structure, component, morphology and electrical bistable properties of the samples are investigated. In the reaction process, n-butyl mercaptan is not only used as a sulfur source but also used as the surfactant. X-ray diffraction (XRD) test indicate that the obtained sample is MoS2 with hexagonal system. The sheet-like morphology is confirmed by the transmission electron microscopy (TEM) and atomic force micros (AFM). And the bigger nanosheets are self-assembled by the lesser nanosheets. The absorption spectrum of the sample is tested and the location of absorption peak reveals that the sample is 2H-MoS2. Electrical bistable device is fabricated by the mixture of prepared nanosheets and polyvinylcarbazole (PVK). And the device exhibits obvious electrical bistability by I-V test.
