Functional improvement of single-walled carbon nanotubes coated on polyimide Kapton HN was studied by means of cyclic cryogenic treatment. Immersing in liquid nitrogen at 77 K joining in heat annealing at 500 K induced the increase of D–G ratio and electrical conductivity in conjecture to the partial remedial junction with the coexisted stiction on surface. The coated thickness was deliberately able to adjust associated with cycling number of cryogenic treatment through the sequential detachment from the outmost layer owing to the axial shrunken effect by new atomic cross links at defects derived from the close bonding distance.
