Abstract
A hierarchical hydroxyapatite inorganic radiative cooling (HIRC) metapaper achieves efficient radiative cooling and enhanced thermal dissipation to accelerate heat release.
Claims20
A method of fabricating a hierarchical hydroxyapatite (HAP) inorganic radiative cooling (HIRC) metapaper, comprising the steps of:
- synthesizing HAP fibers using a calcium oleate precursor in a solvothermal process;
- and
- transforming the HAP fibers into a metapaper sheet comprising hierarchically structured HAP fibers.
A hierarchical hydroxyapatite inorganic radiative cooling (HIRC) metapaper for radiative cooling and heat dissipation comprising hierarchically structured HAP fibers fabricated using a calcium oleate precursor solvothermal process.
