“…The mechanical properties of BC/PBT biocomposites enhanced significantly after ball milled and the properties are comparable to traditional composite, that is, talc/PBT as shown in Table S1, Supporting Information. The irregular shaped and sharp corners of BC can be reduced and changed into a more spherical shape after milling . This reduces the stress concentration factor of the BC filler in the polymer.…”

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.

“…In the production of the biocarbon, the Miscanthus harvested in Ontario was treated in a continuous pyrolysis equipment in a nitrogen environment at 600 to 650 °C for 10–20 min until the biomass was fully charred. The material obtained was ground with a hammer mill to pass a 1/64 inch (0.4 mm) screen [ 11 ]. PHBV (ENMAT Y1000P injection grade), with a density of 1.25 g/cm 3 , was procured from Tianan Biologic Materials, Ningbo, Zhejiang, China.…”

“…In the present work, we explore the use of biocarbon, a carbon-rich material obtained by the incomplete combustion of biomass, as a filler in PHBV. Recent studies have demonstrated that biocarbon can be a renewable alternative to carbon black, which is widely used in the industry as a colorant and filler in automotive parts and rubber products [ 11 , 12 ]. Biocarbon is a promising option for entrapping carbon, and provides numerous opportunities for use in a variety of sectors, notably in soil amendment, catalyst, energy storage devices, and polymer composites [ 13 , 14 , 15 , 16 ].…”

Miscanthus biocarbon (MB), a renewable resource-based, carbon-rich material, was melt-processed with poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) to produce sustainable biocomposites. The addition of the biocarbon improved the Young’s modulus of PHBV from 3.6 to 5.2 GPa at 30 wt % filler loading. An increase in flexural modulus, up to 48%, was also observed. On the other hand, the strength, elongation-at-break and impact strength decreased. Morphological study of the impact-fractured surfaces showed weak interaction at the interface and the existence of voids and agglomerates, especially with high filler contents. The thermal stability of the PHBV/MB composites was slightly reduced compared with the neat PHBV. The biocarbon particles were not found to have a nucleating effect on the polymer. The degradation of PHBV and the formation of unstable imperfect crystals were revealed by differential scanning calorimetry (DSC) analysis. Higher filler contents resulted in reduced crystallinity, indicating more pronounced effect on polymer chain mobility restriction. With the addition of 30 wt % biocarbon, the heat deflection temperature (HDT) became 13 degrees higher and the coefficient of linear thermal expansion (CLTE) decreased from 100.6 to 75.6 μm/(m·°C), desired improvement for practical applications.
