Abstract

The development of phase change materials (PCMs) with high energy density is of great importance for thermal or solar energy storage. In this work, we report for the first time the exploitation of fatty amines (FAs) as a new category of organic PCMs. FAs with carbon number in the range of 12-36 have extremely high latent heat (230-437 kJ kg-1), which is far higher than most of organic PCMs reported to date. The phase transition temperature of these FAs were measured to be in the range of 27.4-71.6 °C with very low supercooling degree (<10 °C). Taking advantages of these inherent feature, FAs may have great potentials as promising energy storage medium for thermal or solar energy storage especially under mild conditions. Based on the plentiful chemistry of amino groups of FAs, we also proposed a new strategy for preparation of form-stable PCMs composites with enhanced FAs uptake due to the strong electrostatic interaction between basic amino groups of FAs and acidic groups of supporting materials, which may also open a new and versatile route to the construction of FAs-based PCMs composites for renewable and sustainable energy saving systems.
