In times of global warming,hummanity needs to develop systems tongenerate and store energy in a green andnefficient way. Phase Change Materials(PCMs) have been extensely studied and applied in modern constructions as they can absorb heat during day and release it at night for keeping temperature between confort levels. PCMs can be incorporated in many components of buildings such as fillerof radiant floor, radiant panels, temperature regulating concrete, and smart windows. We propose to develop polymer coatings for smart windows latent heatstorage1 by incorporating eicosane (C20) into a host matrix of poly ethylene glycol dimethacrylate (PEGDMA). C20 presents anmelting temperature of 37 °C and latent heat of fussion of 232 j/g. However, C20 is highly uncompatible with the PEGDMA matrix and leads to leakage through the matrix when melting. Hence, encapsullation in ethylene glycol dimethacrylate (EGDMA)is proposed in order to obtain a material with PCM properties that can be easily dispersed in liquid reactive monomers for further polimerization by visible light at room temperature.
