采用原子层沉积（ALD）和水热相结合的方法在碳纤维织物上制备了氧化锌（ZnO）纳米阵列，并对其进行了表征。采用原子层沉积法在碳纤维表面制备了一层共形的ZnO种子层，并利用场发射扫描电子显微镜（FESEM）对其进行了表征。采用水热法在碳纤维上生长了ZnO纳米阵列。通过调节水热合成工艺参数，包括反应物浓度和溶液温度，可以控制ZnO纳米阵列的形貌，形成纳米线和纳米棒。FESEM表征表明，所合成的ZnO纳米线和纳米棒具有纤锌矿结构，均匀分布在碳纤维表面。ZnO纳米阵列的长径比被控制在44和270之间。热重分析测试表明，ZnO纳米阵列的生长增加了约10%的额外重量的碳纤维。
The paper presents the synthesis and characterization of zinc oxide (ZnO) nanoarrays on carbon fiber fabrics using the combined atomic layer deposition (ALD) and hydrothermal methods. A conformal ZnO seed layer was first synthesized using the ALD method on carbon fiber surfaces, then characterized by field emission scanning electron microscope (FESEM). ZnO nanoarrays were grown on the carbon fibers using the hydrothermal method. The morphology of ZnO nanoarrays in the form of nanowires and nanorods was controlled by adjusting hydrothermal synthesis parameters, including the concentration of chemical reagents and solution temperature. The FESEM characterization showed that the synthesized ZnO nanowires and nanorods had a wurtzite structure and uniformity distributed on the surface of carbon fibers. The length to diameter ratios of the ZnO nanoarrays were controlled between 44 and 270. The thermogravimetric analysis tests showed that the growth of ZnO nanoarrays added about 10% additional weight to the carbon fibers.
