采用均匀沉淀法制备了碳纳米管(CNTs)负载氧化锌(ZnO)粒子复合材料,并利用扫描电子显微镜(SEM)、X光衍射分析(XRD)以及热失重分析(TGA)手段对复合粒子进行了表征。研究结果表明:锌离子浓度取0.4mol/L至1.0mol/L时,所得复合材料中的氧化锌粒子大小均匀细小,分散性较好,形貌以粒状为主,大小在40nm左右;纳米氧化锌粒子与碳纳米管结合力较强,CNTs/ZnO复合材料在超声作用下能够稳定存在;反应时间越长,氧化锌粒子含量越高,晶粒越大;热解温度越高,热解时间越长,氧化锌晶粒尺寸越大。
Carbon nanotubes (CNTs) -supported ZnO particles were prepared by uniform precipitation method. The composite particles were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermal gravimetric analysis (TGA) Characterization. The results show that when the concentration of zinc ion is 0.4mol / L to 1.0mol / L, the size of the zinc oxide particles in the obtained composite material is small and uniform, the dispersity is good, the morphology is granular, and the size is about 40nm; Zinc particles and carbon nanotubes with strong binding, CNTs / ZnO composite under the action of ultrasound can exist stably; the longer the reaction time, the higher the content of zinc oxide particles, the larger the grain; pyrolysis temperature is higher, pyrolysis time The longer the larger the zinc oxide grain size.
