Layered Nanostructures Containing PCM

Popis výsledku v původním jazyce

In order to reduce the problems due to thermal fluctuations, it is essential to effectively store heat energy. The latent heat energy storage realized using a phase change material (PCM) is one of the most effective techniques of energy storage because of high energy storage density. PCM are capable to store thermal energy as a result of phase changes (liquid / solid or solid/solid). For ensuring the comfort of people or protection of special devices in extreme or suddenly changing external thermal conditions the structures containing these materials are used. The systems containing PCM can be fibers, special layers or surface coatings. Recently, nano-membranes with controlled porosity have also been used for these purposes. The quality of these membranes is related both to their construction (especially porosity) and their chemical composition. The overall thermo-insulating efficiency is also strongly influenced by the incorporation of these membranes into textile structures where one of the decisive factors is the thickness and porosity of the fibrous component. The aim of the contribution is to describe the development of "smart" heat storage composite structure containing PCM loaded layer, barrier nano layers avoiding leakage and conductive layers enhancing thermal conductivity and improving electromagnetic shielding potential. One application of these composite structures is creation of special cases for portable electronic devices (laptops, smartphones) protecting against sudden heat shocks and avoiding identification of their presence inside.
