碳纳米管在碳纤维纸上的生长研究

Study on the Growth of Carbon Nanotubes on Carbon Fiber Papers

采用酞菁铁(FePc)作为碳源和催化剂源,利用化学气相沉积(CVD)法在碳纤维纸(CFP)上生长碳纳米管(CNTs),从而制备了碳纳米管/碳纤维纸复合材料,并利用扫描电镜(SEM)测试、X射线衍射(XRD)测试、接触角测试、电导率测试和孔隙率测试等方法对其结构和性能进行了表征.结果表明,碳纳米管能在碳纤维纸表面生长;表面生长碳纳米管后,碳纤维纸的疏水性、孔隙率和电导率均有所提高.

The carbon nanotubes （CNTs）/carbon fiber papers （CFP） composites are prepared by chemical vapor deposition （CVD） method using iron phthalocyanine （FePc） as the carbon and catalyst sources.The structures and properties of CNTs/CFP composites are characterized by the scanning electron microscope （SEM） testing,X-ray diffraction （XRD） testing,contact angle testing,conductivity testing and porosity testing.The results show that the carbon nanotubes can grow on the surface of carbon fiber papers.Compared to the carbon fiber papers,these CNTs/CFP composites have better hydrophobicity,porosity and conductivity.
