phase change materials in wood plastic composites

Leakage control and characterization of form stable phase change ...phase change materials (PCM) have a role in lowering energy use in buildings by storing and releasing thermal energy. However, leakage of PCMs when in the melt phase is an issue that must be controlled for widespread adoption. Two approaches have been explored in this research, polymer(matrix)/polymer(PCM) binary blends and wood/polymer(matrix)/polymer(PCM) ternary composites. The test materials were prepared using a combination of extrusion, torque rheometer ...

An Experimental Study on the Thermal Performance of Phase ...Abstract: We assessed the usefulness of phase-change material (PCM)-based thermal plates fabricated from wood-plastic composites (WPCs) in mitigating the urban heat island effect. The thermal performance of plates containing PCMs with two different melting temperatures and with two different albedo levels was evaluated. The results showed that the PCM with a melting temperature of 44 °C maintained lower surface and inner temperatures than the PCM with a melting ...
