摘要

Burning plant waste engenders a hefty influence on the production of greenhouse gases, including carbon dioxide (CO2). Reducing atmospheric CO2 concentrations is a major challenge. Biochar production from plant waste is one of the most efficient ways to absorb and sequester atmospheric carbon. Biochar not only removes carbon dioxide from the environment but also stores it in a stable, solid state using natural processes. In the study, sustainable Micro–Nano Hybrid biochar materials (M-NHBMs) were developed from leaves of Iraqi date palm ‘Zahidi’ by a pyrolysis technique, resulting in a particle size range of 300 nm–5.5 μm. M-NHBMs were then incorporated into polypropylene with concentrations (0.01, 0.03, and 0.05 wt%) via extrusion and heat pressing to produce M-NHBMs -PP nanocomposite panels. These panels were subjected to physicochemical (SEM, XRD, FT-IR, DSC, tensile, flexural, and impact) and electrical studies in the lab. SEM revealed a homogeneous distribution at 0.03 wt% composite and enhanced cleavage signatures at the 0.05 wt% composites. XRD confirmed the stability of the α-PP phase with slight peak broadening, while FTIR indicated an increased CH-COC peak at 0.05 wt% nanocomposite. DSC showed stability in the melting point with a slight increase in a composite of 0.05 wt%. Thermal conductivity was recorded with an increment from 0.382 W/m ·°C to 0.03 wt% composite. Mechanical study exhibited highest tensile strength (49.2 MPa), tensile modulus (2.0 GPa), flexural strength (54.6 MPa), and impact strength (36.32 kJ/m²) with a 0.03 wt% sample, followed by the 0.05 wt% sample (flexural modulus of 452 MPa), whereas the 0.01 wt% composite demonstrated superior impact strength., and electrical conductivity rose from 1E‑15 to 1E‑10 S/m, with a dielectric constant of 2.2 to 2.5. The produced physicochemically and conductive M-NHBMs -PP composites established a practical usage in the automotive exterior parts industry to reach industrial sustainable development goals (SDGs).
