dc.description.abstractIn this research, Pinus nigra solid wood (SW) and myristic acid (MA) were prepared as a shape stable phase change material (PCM) using a vacuum impregnation method. Three different concentrations of wood samples such as 15 %, 30 % and 60 % were impregnated and a minimum of 8 % and maximum of 22 % weight gain was obtained. The impregnated samples were characterised by scanning electron microscope (SEM), fourier transform infrared spectrometer (FTIR), X-ray diffractometer (XRD) and differential scanning calorimeter (DSC) analyses and water uptake, resistance to fungal decay, modulus of rupture, modulus of elasticity, compressive and tension strength parallel to the fibers of the samples were tested. The maximum weight increase after impregnation was 25 % and 60 % for the water uptake test samples. The most satisfactory sample was the 60 % modified wood which solidified at 53.50 C with a latent heat of 26.1 J/g and melted at 51.01 C-degrees with a latent heat of 24.7 J/g (medium -temperature zone (buildings fields)). After impregnation, FTIR and XRD analyses revealed no chemical interaction between MA and the wood. Wood was decomposed in a single stage at 367 C, and MAmodified wood was decomposed at two different temperatures: 181-198 C and 365-372 C. At 60 % concentration, MA -modified wood samples showed resistance to T. versicolor fungus, and weight loss of less than 5 % was obtained. After 264 h in the water, the hygroscopic tests demonstrated that the MA/SW composite exhibited low water uptake and good anti -swelling efficiency (ASE). Wood samples impregnated with 60 % MA rose in modulus of rupture and modulus of elasticity, whereas compression and tension parallel to grain values decreased by 7 % and 5 %, respectively. The improvements in heat conductivity are almost 64 % more than the control wood (0.15 W/mK).
