报道了采用可再生的天然前驱体(椰子油),通过化学气相沉积制备一种"高长径比" 的新型碳管结构,炭微管(CMTs)的方法. CMTs合成工艺:N2气氛,合成温度 1175℃,流速100mL/min,二茂铁为催化剂.合成的CMTs利用SEM, EDX, TEM, 和 Raman 光谱表征.结果表明:合成的CMTs的直径为1. 7μm ～2. 1μm, 并具有高的长径比.
The synthesis of a new class of carbon with tubular morphologies is reported. Carbon microtubes (CMTs), having a high aspect ratio were prepared from a natural renewable precursor (coconut oil) by chemical vapor deposition. The CMTs were synthesized in a nitrogen atmosphere at a temperature of 1175℃ and at a flow rate of 100mL/min using ferrocene as catalyst. The synthesized CMTs were characterized by SEM, EDX, TEM, and Raman spectroscopy. The internal diameters of the tubes are around one micron and the external diameters were in the range of 1. 7μm to 2. 1μm.
