“…However, it improved the modulus (both tensile and flexural). This was due to the reduction of intra-particle distances as a consequence of the inclusion of the higher amount of reinforcing constituents (Ho et al 2015). Application of rice husk to biochar/PP composite had a positive correlation with flexural strength and tensile/flexural moduli.…”

“…Manufacturing of biochar-based polymeric composites takes advantage of the porous surface structure allowing molten polymer to flow into them and consequently creating a mechanical interlocking between the matrix and the reinforcement. Moreover, the high surface area of biochar produced from high-temperature pyrolysis aids the dispersion of the particles in the polymer matrix (Ho et al 2015). While the physical structure of biochar has been utilized for enhancing the mechanical properties of polymeric composites, its inherent carbonaceous nature, stable C-C covalent bonds amongst carbon molecules, and aromatic rings with high bond energy could be beneficial for imparting fire resistance to the composites.…”

Four biomass wastes (rice husk, coffee husk, coarse wool, and landfill wood) were added with biochar and polypropylene (PP) to manufacture biocomposites. Individual biomasses were tested for their combustion behavior using cone calorimeter. Biocomposites were analyzed for their fire/thermal, mechanical, and morphological properties. Wood had the most desirable comprehensive effect on both the mechanical and fire properties of composites. In particular, wood and biochar composite exhibited the highest values of tensile/flexural properties with a relatively low peak heat release rate. In general, application of waste derived biochar and biomasses drastically reduced the susceptibility of neat PP towards fire.

“…The BC applications that have been studied and reported include absorbents supercapacitors, enzyme immobilization, and so forth. Some of the investigated and reported BC feedstocks are generated from bamboo, Miscanthus grass, wood, perennial grasses, and chicken feathers . There are significant differences in the properties of BC based upon the different biomass sources .…”

Sustainable biocomposites have gained considerable interest as an alternative to conventional composites in recent years due to their cost‐effectiveness and environmental friendliness. The aim of this study was to investigate the performance and durability behavior of biocomposites from sustainable biocarbon (BC) as compared to conventional established fillers. The poly(butylene terephthalate) (PBT) and its composites reinforced with BC, talc, and glass fiber (GF) were prepared and the durability performances was investigated. The study showed that BC/PBT biocomposites provided a lighter weight alternative to traditionally used fillers. After undergoes thermo‐oxidative aging, the mechanical properties of BC/PBT biocomposite were deteriorated. The GF/PBT showed the most stable in retaining its mechanical properties in comparison to the talc/PBT and BC/PBT. The aging behavior and mechanism of the PBT composites were discussed. This study provides further insight on the durability‐related properties progression of biocomposites as compared to traditional used fillers. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…Bamboo charcoal (BC) is a well-suited reinforcement material for polymers (Ho et al 2015) and WPCs ) because of its high porosity, high resistance to moisture, and high strength, among other factors. The strong interfacial adhesion between BC and polymers could increase the strength and decrease the water absorption of WPCs (You and Li 2014).…”

The physical-mechanical properties of bamboo-polyethylene composites (BPCs) change depending on the environmental temperature and exposure to moisture during outdoor use. In this study, the water absorption, density, mechanical properties, and wear rate of the composites were tested after immersion in water, and four water temperatures were examined. Bamboo charcoal (BC) was used to improve the properties of the BPCs after hydrothermal aging. The composites were improved because of the strong interfacial interactions between the BC and polymers. The experimental results showed that the water diffusion rate accelerated as the water temperature increased. The BC reduced the water absorption at all of the water temperatures and the diffusion coefficient at temperatures above 39 °C. The wear rate of the composites first increased, and then decreased as the water temperature increased. The density and flexural properties decreased with an increased hydrothermal aging temperature. Overall, hydrothermal aging decreased the water resistance and mechanical properties. Additionally, these effects were enhanced as the water temperature increased, but were countered by the incorporation of the BC.
