| 摘 要： | 采用化学镀镍对碳纤维(Carbon fibers,CNFs)表面金属化,研究不同厚度的表面金属化碳纤维的场发射性能。实验结果表明,碳纤维表面金属化后体电阻率明显降低,场发射性能显著提高;厚度不同的金属化碳纤维的场发射性能不同。当化学镀时间为30 min,镍金属膜厚约3.25μm时,碳纤维体电阻率ρ降至1.35×10-4Ω.cm,场发射性能最优,当电压为638 V时出现亮点,电压为1 425 V时,亮度最高达988 cd/m2。

| Abstract: | Carbon fibers(CNFs) were surfacial metallized by electroless deposited with nickel,and their field emission properties were investigated by diode test.The results indicated that the different nickel thicknesses of CNFs were affected on their field emission properties,which the volume resistivity of CNFs was decreased and field emission property was increased,respectively,after CNFs were surfacial metallized.It was found that CNFs owned the best field emission properties after electroless depositing for 30 m... |
