Publication Highlights

1. This article introduces a groundbreaking approach to fabricate Shape-Stabilized Phase Change Materials (SS-PCMs) using a single screw extruder, opening new possibilities for Thermal Energy Storage (TES) applications.
2. The research presents seven distinct formulations of polymer-based SS-PCMs, utilizing high-density polyethylene (HDPE) and polyoxymethylene (POM) as matrices, microencapsulated PCM, and additives like graphite and magnesium hydroxide.
3. The study demonstrates the remarkable chemical stability of HDPE-based composites, making them suitable for thermal cycling up to 1000 cycles. Furthermore, the incorporation of magnesium hydroxide aids in increasing thermal stability and PCM storage capacity.
4. The article discusses trade-offs in composite properties, such as how the addition of graphite enhances thermal conductivity but reduces PCM storage capacity. These insights are crucial for tailoring SS-PCMs to specific applications.
5. Highlighting the significance of the research, the article concludes that extrusion is a promising manufacturing route for SS-PCMs. This breakthrough paves the way for commercializing TES composites while emphasizing the need for further parameter studies to optimize TES attributes.
