Mechanical container energy storage pigment

Methaapanon et al. studied the microencapsulation via sol-gel emulsion and spray-drying of methyl palmitate and n-octadecane using silica as the shell. The material had the potential to be used as a thermal energy storage material for passive cooling applications.

Thermal Energy Storage (TES) refers to a collection of technologies that store thermal (heat or cold) energy for subsequent use either directly or indirectly through energy conversion processes. TES technologies are usually classified, according to the TES materials used for storing the thermal energy, into three categories [1, 2]:

Polymers are the materials of choice for electrochemical energy storage devices because of their relatively low dielectric loss, high voltage endurance, gradual failure mechanism, lightweight, and ease of processability. An encouraging breakthrough for the high efficiency of ESD has been achieved in ESD employing nanocomposites of polymers.

We reported on the use of chemically controlled melanins (DHI- and DHI/DHICA-melanins) processed by solid state polymerization as sustainable organic redox materials for light-assisted pseudosupercapacitors where the storage performance of the device is improved under solar light [ 25 ].

The obtained decanoic acid/PUF microcapsules had a good thermal energy storage capacity, however, they did not have enough mechanical properties to avoid the decanoic acid leak from the core. The microcapsules broke during the charging process at 95 °C due to their thin wall shells.
