Abstract

The invention relates to flexible PCM sheet materials having a high latent thermal energy storage density for the purpose of heat management. The flexible PCM sheet material includes a flexible supporting structure and phase-change-material elements arranged thereon separately in a specific geometry. The phase-change-material elements are geometrically defined structures composed of polymer-bound phase-change material. The flexible PCM sheet materials are characterized by a high latent heat storage capacity and optimized thermal conductivity, are dimensionally stable even in the event of temperature changes and after phase transitions, can be rolled, folded, wound, or cut to size without problems, and can be transported, stored, processed, or used in a single layer or in multiple layers.
