Moreover, polymer dispersed liquid crystals (PDLC) have been extensively studied as promising candidates new materials for application in the field of thermo- and electro-optical devices, such as optic shutters, smart windows, optical sensors, memories and flexible display devices. 

Thermal Management Subsystem - Provides the heat rejection, thermal isolation, and supplemental heating needed to keep the different Reactor Module elements within temperature limits. The thermal management subsystem would include insulating materials (insulation, multi-layer blankets, spacers), surface thermo-optical materials (paints, coatings, treatments, etc), conductive and isolating materials, and probably more active elements such as heaters, temperature sensors and heat pipes. 

Temperature assessment performed by fibre-based sensors can be implemented also by optical technology. One of the promising approaches is coating of FBG fibres with thermo-sensitive substances such as a mixture of methyl ethyl ketone peroxide and cobalt naphthenate. Optical estimation of temperature measurements ensures high accuracy of the results, but the functional coating enhances the performance of the sensor (Li et al., 2012).
