Abstract

Nitrogen doping in carbon nanotube (CNT) fibers using pyrolyzed ionic liquid induced interfacial hydrogen bonding between individual CNTs, enhancing mechanical properties and electrical conductivity simultaneously. In particular, the nitrogen doped CNT fiber using the ionic liquid BMI-I exhibited about 104%, 714%, and 38% increased tensile strength (0.65 N/tex), elastic modulus (83 N/tex), and electrical conductivity (1350 S cm(-1)), respectively, compared to pristine CNT fiber.

摘要

使用热解离子液体在碳纳米管（CNT）纤维中进行氮掺杂，可诱导单根碳纳米管之间形成界面氢键，同时提高机械性能和电导率。特别是，与原始碳纳米管纤维相比，使用离子液体BMI-I的氮掺杂碳纳米管纤维的拉伸强度（0.65 N/tex）、弹性模量（83 N/tex）和电导率（1350 S cm(-1)）分别提高了约104%、714%和38%。
