Paraffin wax as phase change material

WebPhase Change Materials (PCMs) are wax-like thermal compounds that change phase at a specifically formulated temperature. Typically PCMs are silicone-free, paraffin-based wax materials, but can also be acrylic based. WebTo address the leakage issue of paraffin phase-change materials in thermal management, a monolithic MTMS-based silica aerogel (MSA) is employed to encapsulate paraffin through a facile impregnation process. We find that the paraffin and MSA form a physical combination, with little interaction occurring between them. The prepared no-leakage paraffin/MSA …
