Abstract: The preparation and phase change kinetics of NPG/montmorillonite composite materials for energy storage were studied. XRD、IR and DSC have been used to characterize the structure and test the property of energy storage and phase change velocity. The results showed that it has comparatively greater phase change velocity, weak plastic crystal weightlessness and larger phase change enthalpy. It is a new type organic-inorganic nano-composite materials for energy storage which has the latent heat storage property of NPG and the obvious heat storage and filling property of montmorillonite.

Key words: composite materials for energy storage, neopentylglycol, montmorillonite
