Release time:2021-07-17 Affiliation of Author(s):中南大学 Journal:材料导报 Key Words:热解炭 反应温度 滞留时间 Abstract:以等温法进行化学气相沉积(CVD)，研究了过程参数(反应温度、碳源气浓度以及炉内气体的滞留时间)对热解炭结构的影响。实验表明，以丙烯为碳源气，保持炉内气体的流动为层流运动方式，在中等温度(880°C)、 中等滞留时间(2.19s)以及碳源气与载气体积比为 1:3时，能得到粗糙层(RL )结构的热解炭；碳源气裂解为小分子后，在气相中通过加成、聚合、脱氢环化等反应生成苯及含有六元环的芳香烃 ，才能沉积得到结构较好的热解炭 Indexed by:Journal paper Discipline:Engineering Document Type:J Volume:24 Issue:12 Page Number:53-55 Translation or Not:no Date of Publication:2010-12-02 Included Journals:EI -
