Abstract
A method for tuning the thermal conductivity of a nanolayered material is presented. The method includes a step of intercalating the nanolayered material with cations, based on a correlation between cation loading density and thermal conductivity. A bond coat of a thermal barrier system is also disclosed. The bond coat includes a nanolayered material intercalated with cations at a specified loading density based on a correlation between cation loading density and thermal conductivity.
