PCM Integration

Since we have obtained a sample of BASF's Micronal microencapsulated PCM, I have been researching how it is possible to actually use it in a material. Micronal itself is available in two different forms, a liquid form where the microcapsules are dispersed in water, and a powder form. The two can be integrated into different materials which are best suited for their type. The powder form we have obtained is usable in a dry blend like plaster or cement mortar.

BASF recommends that Micronal powder works properly when mixed at a density of 250-350 kg/m^3. If it is necessary to convert the powder back into liquid form, it needs to be dispersed in water at a ratio of 4.2(micronal):10(water).

I am more interested in the integration of PCMs into glass, or being incorporated into a transparent material. I have been looking at how GlassX does this, but the drawings do not tell a whole lot.

After speaking with a professional on the matter, I have concluded that the integration of photonic lattice technology with PCMs may yield interesting results, but is just not feasible at this time due to the high area/volume price. There is some application of PCMs with lattices at a very minimal scale to enhance communications within processors at a nanoscale. The shift between liquid and crystal state allows the heat of the exchange to be minimal, and the overall process to work faster.

Since I never fully explored the application of thermochromic dyes or pigments, I would like to go back and explore the addition of these to my system. A sample of these is certainly easier to procure than photonic lattices - sources are widespread, such as http://www.colorchange.com/
