Abstract
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.
