Engineered Wood Material with Bio-Based Phase Change Material and Micronised Copper for Building Applications

Nazari, Meysam; Jebrane, Mohamed; Terziev, Nasko

Abstract

In this study, pine sapwood was first impregnated with micronized copper (Cu) solution at concentrations of 5 and 10%, the samples then dried and impregnated with ethyl palmitate as a bio-based phase change material (BPCM). The leakage test showed slightly less leakage in this scenario compare to controls without copper. The mould test showed using copper solution, significattly improves the resistance of the composites to mould growth. Thermal tests showed using BPCM improves thermal conductivity and thermal mass of the composites, enabling them to store and release energy within the temperature range of 20-25ºC. It is observed that the copper did not improve thermal conductivity, and 5% copper showed the best performance in thermal mass improvement.
