Thermal-lens spectrometry was used to characterize thermal diffusivity and thermal conductivity of aqueous nanodiamond dispersions at the level of mg/mL, accompanied by heat capacity, density, and viscosity measurements and modelling. The data from thermal lensing corresponding to thermal equilibrium show 3 – 7 % increase in thermal conductivity of the studied dispersions, show good precision and agree with the existing data.
Keywords: nanodiamond nanofluid, thermal lensing.
