Process Know-How for Manufacturing of Micro-Encapsulated Phase Change Materials (M-PCM)

The purpose of developing microencapsulated phase change materials (MPCM) is to enable efficient thermal energy storage and regulation in a stable, form-compatible. Additionally, advanced systems such as silica-based MPCMs offer superior fire resistance, mechanical strength, and compatibility with inorganic construction materials, making them highly suitable for scalable and sustainable building applications.

Technology provides a process know-how for the manufacture of micro-encapsulated phase change materials (M-PCM) used for thermal energy storage and temperature regulation applications. The process involves encapsulating phase change materials such as paraffin or other organic/inorganic PCMs within a protective polymer shell through controlled microencapsulation techniques. The resulting microcapsules exhibit latent heat storage capacity, improved thermal stability, and resistance to leakage during phase transition. The developed process enables the production of uniform, stable microcapsules that can be easily incorporated into building materials, textiles, coatings, and other composite systems to enhance thermal management and energy efficiency. The technology focuses on scalable manufacturing methods, optimized encapsulation parameters, and improved durability of the microcapsules for practical applications in construction and energy-efficient systems.

The micro-scale size significantly increases the surface area, leading to faster heat absorption and release, which enhances thermal responsiveness. MPCMs can be easily incorporated into various matrices such as gypsum boards, concrete, coatings, and textiles without affecting structural integrity, enabling multifunctional materials with energy storage capability. The encapsulation also improves chemical and environmental resistance, protecting the PCM from oxidation and degradation. Additionally, MPCMs contribute to improved indoor thermal comfort by reducing temperature fluctuations and lowering energy demand for heating and cooling systems. In advanced systems, especially silica-based MPCMs, added benefits include better fire resistance, mechanical strength, and compatibility with inorganic materials, making them suitable for sustainable and large-scale building applications.
