Carbon Nanofiber and its Manufacturing Method

Carbon Nanofiber with Improved Physical Properties by Laser Irradiation and its Manufacturing Method

This technology describes a carbon nanofiber and its manufacturing method, where a sacrificial layer is applied to carbon nanofibers composed of multiple carbon nanotubes, followed by laser irradiation.

Carbon nanofibers have had limitations of lower tensile strength and thermal conductivity compared to single carbon nanotubes.

This technology improves tensile strength, elastic modulus, and electrical and thermal conductivity by inducing plastic deformation in carbon nanotubes through laser irradiation.
