Abstract

CNTs and CNT-MgO, CNT-MgO-Ag, and CNT-MgO-Ag-BaO nanocomposites were grown on alloy substrates using an electrophoretic deposition method and their field emission (FE) and hydrogen sensing performances were investigated. The obtained samples were characterized by SEM, TEM, XRD, Raman, and XPS characterizations. The CNT-MgO-Ag-BaO nanocomposites showed the best FE performance with turn-on and threshold fields of 3.32 and 5.92 V.μm, respectively. The enhanced FE performances are mainly attributed to the reductions of the work function, and the enhancement of the thermal conductivity and emission sites. The current fluctuation of CNT-MgO-Ag-BaO nanocomposites was only 2.4% after a 12 h test at the pressure of 6.0 × 10 Pa. In addition, for the hydrogen sensing performances, the CNT-MgO-Ag-BaO sample showed the best increase in amplitude of the emission current among all the samples, with the mean I increases of 67%, 120%, and 164% for 1, 3, and 5 min emissions, respectively, under the initial emission currents of about 1.0 μA.

摘要

采用电泳沉积法在合金基底上生长了碳纳米管（CNTs）以及碳纳米管-氧化镁（CNT-MgO）、碳纳米管-氧化镁-银（CNT-MgO-Ag）和碳纳米管-氧化镁-银-氧化钡（CNT-MgO-Ag-BaO）纳米复合材料，并对它们的场发射（FE）和氢传感性能进行了研究。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）、X射线衍射（XRD）、拉曼光谱和X射线光电子能谱（XPS）对所得样品进行了表征。碳纳米管-氧化镁-银-氧化钡纳米复合材料表现出最佳的场发射性能，其开启场和阈值场分别为3.32 V·μm和5.92 V·μm。场发射性能的增强主要归因于功函数的降低、热导率的提高以及发射位点的增加。在6.0×10 Pa的压力下进行12小时测试后，碳纳米管-氧化镁-银-氧化钡纳米复合材料的电流波动仅为2.4%。此外，对于氢传感性能，在约1.0 μA的初始发射电流下，碳纳米管-氧化镁-银-氧化钡样品在所有样品中发射电流幅度的增加最为显著，在1、3和5分钟发射时，平均电流增加分别为67%、120%和164%。
