A preparation method a tunable transparent terahertz absorption film for enhancing thermal radiation includes: evaporating/sputtering an indium tin oxide (ITO) on one surface of a polyimide film, transferring graphene to the other surface of the polyimide film, preparing one electrode on the graphene, spin-coating an ionic gel, and preparing the other electrode on the ionic gel to form the tunable transparent terahertz absorption film; and changing bias voltages at two ends of the electrode, acquiring a terahertz time-domain signal of the tunable transparent terahertz absorption film to derive an absorption rate of the tunable transparent terahertz absorption film corresponding to the bias voltages, and placing the tunable transparent terahertz absorption film under sunlight/infrared light to acquire a heating effect. The preparation method utilizes the transparent absorption film of a graphene-polyimide-ITO structure to absorb terahertz waves of multiple bands, improving the heating effect.
