1. A substrate having a thin film obtained by:
- mixing carbon nanofibers into an elastomer including an unsaturated bond or a group having affinity to the carbon nanofibers, and dispersing the carbon nanofibers by applying a shear force to obtain a carbon fiber composite material;
mixing the carbon fiber composite material and a solvent to obtain a coating liquid; and
applying the coating liquid to a substrate to form the thin film, the thin film in an uncrosslinked form having a first spin-spin relaxation time (T2n) measured at 110°
C. of 100 to 3,000 μ
sec, a second spin-spin relaxation time (T2nn) measured at 110°
C. of either 0 μ
sec or 1,000 to 10,000 μ
sec, a fraction (fn) of components having the first spin-spin relaxation time of 0.95 or more.

Abstract
A method of manufacturing a thin film, including: mixing carbon nanofibers into an elastomer including an unsaturated bond or a group having affinity to the carbon nanofibers, and dispersing the carbon nanofibers by applying a shear force to obtain a carbon fiber composite material; mixing the carbon fiber composite material and a solvent to obtain a coating liquid; and applying the coating liquid to a substrate to form a thin film.
