螺旋纳米碳纤维的研究进展

摘要

螺旋纳米碳纤维因其杰出的物理和化学特性(低密度、超弹性、高导电率、高比强度、耐热性和化学稳定性)已经引起了人们极大的关注.它们可以被用来作为微磁传感器、电磁波吸收材料、储氢材料和弹性材料等.综述了螺旋纳米碳纤维的制备、影响因素、微观结构和生长机理,并讨论了螺旋纳米碳纤维存在的一些问题.%Helical carbon nanofibers have been attracting tremendous attention due to their novel physical and chemical propertiesdow-desity, super-elasticity, high electric conductivity, high specific strength, heat resistance and chemical stability). They can be used as micro-magnetic sensors, electromagnetic wave absorption materials, hydro gen storage materials and elastic materials, etc. The preparation, influence factors, microstructure, and growth mechanism of helical carbon nanofibers are reviewed. Some problems in the research of helical carbon nanofibers are also summarized.
