Abstract
A thermally conducting composition of the present invention includes (A) a cellulose nanofiber, and (B) at least one type of an inorganic powder selected from a metal oxide and a diamond having an average particle diameter of 50 nm or less. A method for producing the thermally conducting composition includes the steps of preparing a dispersion by adding water or a mixed solvent of water and a hydrophilic solvent to (A) a cellulose nanofiber and (B) at least one type of an inorganic powder selected from a metal oxide and a diamond having an average particle diameter of 50 nm or less; and removing the water or the mixed solvent of water and a hydrophilic solvent from the dispersion. The present invention provides a thermally conducting composition that utilizes a cellulose nanofiber and an inorganic powder having the thermal conductivity at a nano-scale size, can improve the thermal conductivity significantly, and further can have properties such as anisotropy and transparency, and a method for producing the same.
