Wood-based phase change materials (WBPCM) have the potential to significantly reduce energy consumption in plywood structures, but the quest for a streamlined production strategy to facilitate their industrialization remains a formidable challenge. In this work, phase change plywood (PCP) was prepared by phase change adhesive (PCA), in which urea-formaldehyde resin (UF) served as the adhesive and different contents of paraffin wax (PW) as phase change materials (PCM). The use of PCA enabled the efficient and simplified production of wood-based composites with excellent energy-saving properties. By combination of the low thermal conductivity of wood with the energy storage capabilities of PCA, PCP demonstrated a high latent heat capacity of 67.53 J/g at 47.6 °C. 2D correlation Fourier transform infrared (2D FTIR) was carried out to analyze the phase transition mechanism. By adding PCA, the heat transfer time of PCP-3 from 40 to 55 °C was extended by 181%, compared with conventional plywood, which indicated an excellent energy-saving ability. Furthermore, finite element simulation was conducted to statistically simulate the thermal transition process of PCP. Our work presents a strategy for the design of phase change plywood with excellent energy-saving properties, while also enabling large-scale production.

In recent years, graphene has been introduced into phase change materials (PCMs) to improve thermal conductivity to enhance the heat transfer efficiency in thermal energy storage. However, graphenes tend to aggregate in PCMs, leading to the low thermal conductivity efficient enhancement (TCEE), anisotropic thermal conductivity, and deterioration of mechanical performance of PCMs. In this work, we fabricated biomimetic thermally conductive solid− solid PCMs (SSPCMs) by facile blending of the graphene into well-designed polyurethane SSPCMs, in which the graphene established a controllable and highly efficient isotropic thermally conductive pathway based on the π−π stacking between the graphene and the polymer aromatic ring segment. The asfabricated SSPCMs showed high TCEE (156.78%), excellent flexibility (328% elongation at break), high enthalpy value (>101 J/g), and solid−solid phase transition properties, under 2% loading of graphene. The proportion of in-plane to through-plane thermal conductivity can be adjusted by an elaborate design of the aromatic ring segment in polyurethane SSPCMs. We further demonstrated mechanical flexibility and photothermal property of the composites to reveal their potential in practical applications.

“…Nevertheless, several modifications can be applied to enhance PLA's properties, including copolymerization [11,12], particle addition [13,14], polymer blending [15,16], and plasticization [13,[15][16][17].

Nowadays, companies and researchers are concerned about the negative consequences of using synthetic polymers and direct their efforts to create new alternatives such as biocomposites. This study investigated the effect of biobased SiO2 on the properties of poly(L-lactic acid)/SiO2 (PLLA/SiO2) and poly(L-lactic acid)/SiO2/poly(ethylene glycol) (PLLA/SiO2/PEG) composites. The SiO2 was obtained from rice husk incineration and mixed with PLLA at various concentrations (5, 10, and 15 wt.%) via melt extrusion before compression molding. Furthermore, PLLA/SiO2/PEG composites with various PEG concentrations (0, 3, 5, and 10 wt.%) with 10 wt.% SiO2 were produced. The sample morphology was studied by scanning electron microscopy (SEM) to analyze the dispersion/adhesion of SiO2 in the polymer matrix and differential scanning calorimetry (DSC) was used under isothermal and non-isothermal conditions to study the thermal properties of the samples, which was complemented by thermal stability study using thermogravimetric analysis (TGA). Rheological analysis was performed to investigate the viscoelastic behavior of the composites in the melt state. At the same time, tensile mechanical properties were obtained at room temperature to determine their properties in the solid state. DSC and X-ray diffraction analysis (XRD) were combined to determine the crystalline state of the samples. Finally, gas permeation measurements were performed using a variable pressure (constant volume) method to analyze the permeability of different gases (CO2, CH4, O2, and H2). The results showed that SiO2 decreased the PLLA chain mobility, slowing the crystallization process and lowering the gas permeability while increasing Young’s modulus, thermal stability, and viscosity. However, PEG addition increased the crystallization rate compared to the neat PLLA (+40%), and its elongation at break (+26%), leading to more flexible/ductile samples. Due to improved silica dispersion and PLLA chain mobility, the material’s viscosity and gas permeability (+50%) were also improved with PEG addition. This research uses material considered as waste to improve the properties of PLA, obtaining a material with the potential to be used for packaging.
