“…The thermal conductivity of a material is directly proportional to its density [47]. Previous studies have reported similar trends for other particulate composites with different types of fillers, such as graphite [48], aluminum nitride [49], and aluminum [50]. However, the thermal conductivity values of particleboards with AC in this study are lower than those reported for other composites with similar filler contents [49,50].…”

Nowadays, the particleboard industry cannot meet the market’s demand. Therefore, filler materials have started to be used both to conserve raw materials and to enable the use of wood-based boards in different areas. This study investigates the effects of incorporating different ratios of activated carbon (0%, 1.5%, 4.5%, 7.5%) on the properties of particleboards. The physical properties were examined, including density, moisture content, thickness swelling, and water absorption. The results reveal that the density increased with increasing activated carbon content while the moisture content decreased, indicating improved dimensional stability and water resistance. Additionally, the color properties were influenced by activated carbon, leading to a darker appearance with decreased lightness and yellow-blue components. The mechanical properties, such as internal bond strength, modulus of rupture, and modulus of elasticity, showed significant enhancements with the addition of activated carbon, indicating improved bonding and increased strength. Moreover, the thermal conductivity decreased with increasing activated carbon content and improved insulation performance. Scanning electron microscope analysis confirmed the uniform distribution of activated carbon within the particleboard matrix, without agglomeration, positively impacting the mechanical performance. According to the thermogravimetric analysis results, the addition of activated carbon led to a decrease of up to 6.15% in mass loss compared to the control group. The incorporation of activated carbon at a ratio of 4.5% in particleboards confers notable enhancement to their physical, mechanical, and thermal characteristics. These findings contribute to understanding the potential benefits and considerations of using activated carbon as an additive in particleboard production.

“…Polyethylene glycol (PEG) has been used to form a stable suspension of activated carbon macroparticles (ACMP) in paraffin. 18 The effect of ACMP and PEG, as well as combinations thereof, on improving the thermal conductivity of PCM was studied. Various concentrations of components in the range from 0.3 to 2 wt % were used.…”

Various types of surfactants (Tween 20, Tween 80, Span 20, and Span 80) were used as a stabilizing additive in composites based on petroleum asphaltenes and paraffin -a material that has prospects for use as a phase-transition material in thermal accumulators. The influence of surfactants on the structure and morphology of composites, the rheology of their melts, thermal conductivity, and crystallization ability is shown. An increase in thermal conductivity of 9% has been demonstrated. This correlates with the formation of filler clusters in the presence of surfactants. The presence of surfactants in composites with paraffin has a slight effect on the crystal lattice parameters of paraffin in composites, while the introduction of Tween 20 at a concentration of 1% wt. leads to an increase in the degree of crystallinity of paraffin. In melts of paraffin-asphaltene composites, the network of filler contacts contributes to the presence of a pronounced yield strength. The introduction of a surfactant leads to a decrease in the strength of the contact network and an increase in the fluidity of systems, probably due to the presence of surfactant adsorption layers on the surface of the contacting particles.
