摘要
采用催化剂高温分解法,在硅片上成功地制备了碳纳米管薄膜.利用扫描电镜和透射电镜观察表明,所制备的碳纳米管薄膜具有非常良好的定向性、均匀性和定域生长性.详细讨论了制备工艺参数变化对碳纳米管生长的影响.利用碳纳米管薄膜作为阴极材料,给出并分析了碳纳米管薄膜阴极的场致发射特性.
By using the catalyst pyrolysis method, the carbon nanotube film was prepared on the different substrate materials. Seen from the SEM and TEM photo, the prepared carbon nanotube film possesses a better directing property, uniformity and a localization growth property. The effect of the process parameter on the preparation of the carbon nanotube film is discussed. With the carbon nanotube film as cathode materials, the field emission characteristics of the carbon nanotube film cathode are presented and analyzed.
