摘要:
为探寻既可以活化碳纳米管又对其本身的结构与性能影响较小的实验条件,该文对在碳纳米管表面构造缺陷的高温热处理工艺进行了研究。在空气中高温热处理碳纳米管,并尝试不同的温度和保温时间,得到不同的碳纳米管样品。经扫描电子显微镜、透射电子显微镜、激光拉曼光谱仪和红外光谱仪的测试,结果表明:高温热处理能达到活化碳纳米管的目的,在碳纳米管表面和端部产生缺陷,引入含氧亲水基团; 碳纳米管缺陷含量及被氧化的程度受到处理温度与时间的影响,高温可以有效优先活化碳纳米管的端部且较大程度地保留碳纳米管原有的优异特性。
Abstract:
A systematic study on the technique for producing defects on the surface of carbon nanotubes(CNTs)by high-temperature heat treatment is carried out to get an experimental condition that not only can activate CNTs but also has less inference on the structure and performance.Different samples of CNTs are obtained by high-temperature heat treatment in air at different temperatures and for different holding times.The characterization results by scanning electron microscopy(SEM),transmission electron microscopy(TEM),laser Raman spectrometer and infrared spectroscopy show that:high-temperature heat treatment can activate CNTs and produce defects and oxygen-containing hydrophilic groups at the surface and end of the CNTs; the amount of defects and the degree of oxidation in CNTs are affected by the treatment temperature and holding time,and high-temperature heat treatment can activate CNTs at the end preferentially and hold the excellent performance of CNTs.
