Paramaribo thermal conductive phase change energy storage material

Are phase change materials suitable for thermal energy storage?

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

Why is thermal conductivity important for phase change energy storage systems?

Thermal conductivity is a key parameter for phase change energy storage systems to measure how fast or slow the energy is transferred. Many researchers in China and abroad have done a lot of work on improving the thermal conductivity of phase change materials.

How does phase change affect thermal conductivity of composite PCMS?

Furthermore, the thermal conductivity of the composites increases with the increase of phase change temperature. In addition, the thermal conductivity of six kinds of composite PCMs are higher than that of pure paraffin wax and microcrystalline wax.

What is the thermal conductivity of NPC/ma-sa composite PCM?

Moreover, the thermal conductivity of NPC/MA-SA composite PCMs increases by 117.65% than pristine PCM and is about 43.06% larger than that of composites by post synthesis route. The introduction of N heteroatom plays a key role in changing the textural properties of carbon materials.

Do PCMs have a low thermal conductivity?

However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/(m K)) limits the power density and overall storage efficiency. Developing pure or compos-ite PCMs with high heat capacity and cooling power, engineering effective thermal storage devices, and optimizing system integra-tion have long been desired.

How can 0d structure additives improve the thermal conductivity of PCMS?

Owing to possess high thermal conductivity, the addition of a small amount of 0D structure additives supporting materials can significantly improve the thermal conductivity of the initiative composite PCMs . As a result, it can be used as an additive for form stable PCM and as a heat conduction of microcapsule composites.
