Large anisotropy of thermal and electric conductions of the carbon nanotubes (CNTs) paper between in-plane and through-plane direction due to the one-dimensional fibrous structure of CNTs is problematic when the temperature gradient are required for applications such as thermoelectric conversion using Seebeck effect. To control the orientation of the CNT direction, polymer particles are introduced upon paper formation via vacuum filtration method. Thermal and electric conductivity in in-plane direction are decreased as increase the amount of the polymer particles used for the paper formation, while those in through-plane direction are increased. Heat diffusion in the paper are monitored by IR camera and it is found that the larger temperature gradient are observed for the CNT paper with anisotropy control compared to the original paper without anisotropy control.
