Abstract
According to an embodiment of the present disclosure, a multi-acid anionic material-carbon fiber composite comprises carbon nanofibers and multi-acid anionic crystals stuck in the carbon nanofibers. Some of the multi-acid anionic crystals are exposed to an outside of the carbon nanofibers.
Claims1
A multi-acid anionic material-carbon fiber composite, comprising:
- carbon nanofibers;
- multi-acid anionic crystals stuck in the carbon nanofibers, wherein a part of each of the multi-acid anionic crystals is embedded in the carbon nanofibers, and the remaining part of each of the multi-acid anionic crystals is exposed to an outside of the carbon nanofibers,
- wherein 5 to 20 parts by weight of the carbon nanofibers are included relative to 100 parts by weight of the multi-acid anionic crystals, and
- wherein the multi-acid anionic crystals are sodium vanadium phosphate crystals.
