Abstract

The invention relates to a latent heat storage material comprising a first phase change material, at least one second phase change material different from the first phase change material, and an expanded graphite material wherein the first phase change material and the at least one second phase change material are intermixed and the latent heat storage material exhibits a phase transition over a range of temperatures. The invention also relates to a process for the preparation of a latent heat storage material comprising combining a mixture of an expanded graphite material and a first phase change material with at least one different second phase change material.
