What is thermal analysis of microcapsules?

Thermal analysis The microcapsules prepared are intended for use in energy storage, so their thermal characterization is of great interest. It is essential to know the enthalpy of the phase change and their thermal stability.

Are microcapsules based on ZnO containing n-octadecane a phase change material?

In this study, microcapsules based on ZnO containing n-octadecane as a phase change material were synthesized and characterized with regard to their structural, morphological and optical properties according to several synthesis parameters, such as the proportion of precursors, stirring rate and ageing time.

What are the properties of Pu microcapsules?

The surface morphology, melt crystallization, thermal cycling durability, thermal stability and mechanical properties of PU microcapsules were systematically investigated with field emission scanning electron microscope (FE-SEM), different scanning calorimetry (DSC), thermogravimetric (TG) and dynamic mechanical analysis (DMA).

What is the energy storage capacity of C18 microcapsules?

These three samples showed an energy storage capacity of 100%, which means that all the C18 inside the microcapsules is able to store thermal energy and release latent heat. They show an encapsulation efficiency of 21.3%, 19.4% and 23.1%, respectively.

Do microcapsules have a high stability?

The microcapsule samples are powder, so the presence of the phase change peaks in the plots is evidence of the formation of the capsules including the PCMs inside. These thermograms show that the microcapsules present high stability. A small peak can also be seen in the C18@ZnO50/50_750_8 sample at 26.4 °C.

Can nano-encapsulated N-nonadecane be used for thermal energy storage?
