“…Furthermore, both the equilibrium melt temperature and equilibrium torque at steady state increased with increasing WF content but decreased with the addition of lubricant [13]. In the case of other fillers, the incorporation of lignin [18], basalt fiber [3], carbon fiber [19], and vapor-grown carbon nanofibers [20] also enhanced the thermal stability of the polymer matrix. The glass transition temperature, melting point, and degree of crystallinity of the polymers increased with the addition of cellulose nanocrystals or cellulose fibers [21,22,23].…”

The thermal performance of wood–plastic composites (WPCs) with different fiber, different fiber contents, and different lubricants were investigated in this paper. The results show that the thermal degradation temperature, melting temperature, crystallization temperature, crystallinity, and viscosity of WPCs with wood fiber were slightly higher than those of WPCs with floor sanding powder and rice husk. As the wood fiber content increased, the melting temperature and crystallinity of WPCs decreased while the crystallization temperature, viscosity, and pseudoplasticity increased. When the wood fiber content was increased to 60%, the dimensional stability of WPCs tended to be constant, and a higher wood fiber content was not conducive for processing of WPCs. WPCs had a small coefficient of linear thermal expansion at low temperature and demonstrated a good dimensional stability. The presence of lubricant reduced the viscosity and increased the pseudoplasticity of the WPCs, which is advantageous for the dimensional stability of WPCs at low temperature while making it worse for high temperatures.

“…Rasana et al (2019) stated that glass fibers act as a thermal shield and inhibit degradation. The degradation of carbon fibers above 600 °C, which is higher than polyethylene and wood, improves the thermal stability of WPCs (Eibl, 2017;Guo et al, 2019b;Yao et al, 2018). As in previous studies, the thermal degradation of WPCs was retarded with the reinforcement of glass and carbon-woven fabrics (Durmaz et al, 2021).…”

The interest in wood plastic composites (WPCs) has increased in recent years. The utilization of environmentally friendly materials has been of great significance due to the overwhelming pressure on nature. As a widely used material, plastic is, however, easily combustible due to its structure. In this study, WPCs were reinforced with zinc oxide (ZnO) nanoparticles. The effect of higher content of ZnO nanoparticles (1, 3, 5, 10 %) on WPCs thermal stability and fire performance was investigated. Thermogravimetric analysis (TGA) clearly demonstrated that nanoparticles acted as a shield, which inhibited heat transfer and increased the degradation temperature thanks to covering the surface of materials. Free radicals accelerated the thermal degradation of neat-HDPE (high-density polyethylene) by oxidative reactions, while ZnO nanoparticles reduced the degradation velocity. Moreover, the increase in nanoparticle content significantly affected the residue. The fire performance of WPCs was also investigated by the limit oxygen index (LOI) test. While neat-HDPE flamed with dripping, ZnO nanoparticles made flaming difficult for WPCs. Therefore, the LOI values increased with increasing nanoparticle content up to 28.5 %, which indicated the need for more oxygen. The improvement reached up to 54 % compared to neat HDPE. Moreover, the char forming was also improved, which helped enhance the fire resistance. The scanning electron microscope (SEM) investigation indicated that nanoparticles were well dispersed in the matrix. However, the tendency to agglomerate increased with the increase of concentration. The ability of carbonization of wood fiber surface during the combustion also contributed to improving thermal stability and fire performance.

Pinecone is a lignocellulosic forest waste that has industrial value‐added importance in energy and material production. To deepen the functional utilization of agricultural and forestry waste, exploration of materials for high‐performance electromagnetic interference (EMI) shielding prevents pollution from electromagnetic radiations. Herein, low cost, environment‐friendly, and efficient electromagnetic wave absorbing composites were obtained by simple and effective method using agricultural and forestry waste pinecone biochar (PB) as the carbon source and poly (butylene succinate) (PBS) as a biodegradable thermoplastic matrix. The effect of biochar content, biochar chemical and physical modification on properties of composite, especially electrical conductivity and EMI shielding performance have been investigated. Results showed that the electromagnetic shielding property of the material increased with an increase in biochar content, and the value was 54.51 dB when the pine cone charcoal content was 55%. Furthermore, these composites also showed improved thermal stability and adequate mechanical strength. Compared to untreated biochar and add coupling agents, the pickling treatment of biochar was a more effective way to enhance the EMI shielding (to 41.23%) and other properties of the composite. Furthermore, the experimental results show that it is possible to produce fully biodegradable functional polymer composites from agricultural waste.
