Abstract

In recent years, with the growing population base and the increasingly severe ecological environment, energy
storage materials have become a hot topic in the field of material manufacturing, and the market has a great
demand for energy storage materials. But there are still many problems in the technical level. The continuous
development of nanotechnology provides the possibility for the preparation of organic composite phase change
energy storage materials. Therefore, it is very necessary to actively carry out research on the preparation of
organic nanocomposite phase change energy storage materials. The purpose of this paper is mainly to discuss
the preparation of organic nanocomposite phase change energy storage materials. Four samples of Cu-paraffin,
Al-paraffin, C (Cu) -paraffin, and paraffin were selected as the experimental objects, and the types of
nanoparticles were respectively tested Determination, phase change temperature, phase change latent heat and
specific heat determination and composite heat transfer test, compare the data of each group. The results show
that when the number of cycles is 0, the melting phase transition temperature of the Cu-paraffin nanocomposite
phase change heat storage material is 53.8 ℃, the solidification phase transition temperature is 60.4 ℃, the
latent heat of phase change is 197.9KJ / Kg; At 20 times, the melting phase change temperature of Cu-paraffin
nanocomposite phase change heat storage material is 53.1 ℃, the solidification phase change temperature is
61 ℃, and the latent heat of phase change is 197.2KJ /Kg. It can be seen that the Cu-paraffin nanocomposite
phase change heat storage material has superior energy storage effect.
