A functional form-stable phase change composite with high efficiency electro-to-thermal energy conversion

摘要: Abstract A novel solid-to-solid phase change composite brick was prepared by combination of polyurethane (PU) and pitch-based graphite foam (PGF). The carbonaceous support, which can be used for mass production, not only greatly improves the thermal conductivity but promote electro-to-heat conversion efficiency organic materials (PCMs). Our retained enthalpy PCM exhibited a reduced supercooling temperature. investigated differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) electron microscope (SEM). has increased about 8.6% after infiltrating into foam. very stable during cycle test, achieves to 85% at lower voltages (1.5–1.8 V), vastly reduce energy consumption. as-prepared in wear layer test its performance comparing with normal fabric.
