Facile preparation of pitch-derived carbon for high electrically conductive composites via carbon nanotube template

Funds: The project was supported by the National Natural Science Foundation of China (21878001, 22078002, 22108004, 21978002, 22008001)
  • 摘要: 本研究以煤沥青为原料、多壁碳纳米管为结构导向剂,通过炭化制备了形貌和结构可控的煤沥青基碳膜,考察了多壁碳纳米管对导电填料结构及碳膜电热性能的影响规律。研究发现,多壁碳纳米管掺杂导致导电填料的晶格排列有序度增加、晶格间距减小和石墨化程度提高;多壁碳纳米管的引入提高了碳膜的载流子浓度,进而显著提高了其导电性。掺杂2%碳纳米管,可使煤沥青基碳膜的载流子浓度提高3.2倍、电阻降低67%;在5、10和15 V电压下,煤沥青基碳膜的发热温度分别可达44、88和165 ℃,相对未掺杂碳膜分别提高了7、22和70 ℃,显示出极大的应用前景。
