Abstract:
1. A method of producing a carbon nanofiber composite material, comprising: mixing an elastomer which includes an unsaturated bond or a group having affinity to carbon nanofibers with metal particles; and mixing the carbon nanofibers into the elastomer including the metal particles and uniformly dispersing the carbon nanofibers by a shear force at 0 to 50° C. by a method selected from the group consisting of an open-roll method with a roll distance of 0.5 mm or less, a closed kneading method, and a multi-screw extruding kneading method, wherein the composite material is in an uncrosslinked form and the composite material has a first spin-spin relaxation time (T
