 摘要:  以乙炔(C2H2)为碳源,铜溶胶和硫化铜为催化剂前躯体,采用化学气相沉积法(CVD)在玻璃基板上生长纳米碳纤维薄膜。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)和X射线衍射仪(XRD)对产物的形貌与结构进行了表征。结果表明:在反应温度为350 ℃时,制备出了纤维直径为100~200 nm,厚度为3~20 μm的均匀的纳米碳纤维薄膜;随着反应温度升高或者反应时间的延长,纳米碳纤维薄膜的膜厚增厚。

 Abstract: Carbon nanofibers film(CNFs film) were synthesized by the chemical vapor deposition (CVD) using copper sol and copper sulfide as catalyst precursor and acetylene as carbon source on glass substrate. The products were characterized by SEM TEM and XRD. It was observed that CNFs film with diameter of 100—200 nm and thickness of 3—20 μm were synthesized at 350 ℃. The thickness of CNFs film increased with reaction temperature or reaction time increasing.

 Key words: copper sol; copper sulfide; glass substrate; CVD; CNFs film
