Fibrous carbon nanostructure, evaluation method of fibrous carbon nanostructure, and manufacturing method of surface-modified fibrous carbon nanostructure

摘要

The present invention provides a fibrous carbon nanostructure that is easy to undergo surface modification treatment. In the fibrous carbon nanostructure of the present invention, the symmetry coefficient of the peak of the first derivative curve of the thermogravimetric curve obtained by thermogravimetric analysis in a dry air atmosphere is 3.70 or less. Here, the first derivative curve of the thermogravimetric curve may be a temperature derivative curve of the thermogravimetric curve or a time derivative curve of the thermogravimetric curve.
