MPB Communications awarded Patent for new material that passively reacts to ambient temperatures

MPB Communications Inc. has been awarded a US Patent for the invention of a material that helps maintain a thermally stable environment within satellite housings.

The presence and absence of solar energy has the potential to respectively raise and lower internal temperature of any structure “like in your car at different times of the day or year,” explains Wes Jamroz, Director of the Space and Photonics Division at MPBC. “Heating and cooling outside the protection of the atmosphere happens even faster over a more extreme range - from minus 150°C to plus 150°C in a matter of minutes.”

It is preferable to maintain the internal temperature of a satellite between -10°C to +30° to ensure effective operation of communication and control electronics such as processors and transceivers.

MPBC’s patent is for the composition of a special coating (Variable Emittance Thermochromic Material) that adjusts its properties in accordance with the ambient environment. Used in the exterior structure of a satellite housing, the coating will maintain the optimal temperature of   the interior.

Although there are known variable emittance coatings in existence, they differ from MPBCs in that they need to be electrically manipulated to react.  The material MPBC has developed responds passively, which eliminates any additional electronics and reduces the possibility of failure.

The same invention is applicable for a number of terrestrial applications that require regulation of the internal temperature of a structure, housing, protective suite, and/or vehicle.

MPBC hopes to demonstrate its Variable Emittance Thermochromic Material in space within the next few years.
