Paraffin is wrapped up, to form photothermal conversion microcapsules of storing energy through phase change.And the presence that this cladding is typically due to crystal grain makes
It must coat and imperfect, it is easy to which damaged, simultaneously because using as shell material, core material thermal conductivity is lower, so that shell material is converted
Heat can not effectively pass to core material, and pass to surrounding medium, cause energy dissipation.
Few layer two-dimensional material and noble metal nano particles are generally acknowledged optical-thermal conversion material, two-dimensional material absorption spectrum ranges
Ultraviolet-visible-near infrared region can be covered, but can not generally be dispersed in oily phase, it is difficult to as core material filler, generally
As shell material added material, noble metal nano particles thermal conductivity is high, but its spectral absorption only covers short-wavelength visible light region,
Therefore homogenous material and optothermal material are that the mode of shell material is limited to the energy utilization of sunlight.
