In the present project, the encapsulation of a phase change material in a polymeric matrix is investigated in order to test its usability as a solid energy storage material. Commercial paraffin wax was used as phase change material, polyethylene and a copolymer were used as encapsulating materials. Additionally, there were also some samples investigated, with the use of graphite powder. Different compositions of the compound were examined. The intention was, to study and compare the different compositions, especially: the possibility of producing the compound; long-term stability; mechanical stability; thermal properties like the melting point and the melting range, the latent heat of fusion, the thermal conductivity and the heat capacity. In particular, the influence of different parts by weight of the copolymer and of the graphite on the properties described above were investigated. Furthermore, a numerical model was developed to predict the heating and cooling behavior of such a compound with the data from a DSC analysis.
