Biochar-Alginate-PVA Nanofiber Mats: Fabrication and Characterization

Purpose: The aims of this study are synesis and determination of characteristic of novel nanofibers incorporating biochar, polyvinyl alcohol (PVA), sodium alginate (ALG), and glyoxal (GO) through electrospinning. Methods: Biochar, known for its exceptional adsorption capacity, was integrated into the polymer matrix to enhance pollutant removal efficiency. Glyoxal was added to improve the nanofibers' electrical conductivity and mechanical strength. Results: The electrospinning process was optimized to produce uniform, bead-free nanofibers by maintaining a ۱۵ cm needle-to-collector distance, a ۲۰ kV voltage, and a ۰.۸ ml/h feed rate. Characterization techniques such as FESEM, FTIR, XRD, and BET were employed to analyze the morphology, chemical composition, and surface properties of the nanofibers. Conclusion: The results confirmed the successful incorporation of biochar into the polymer matrix, revealing unique structural and morphological properties in the composite material. The research describes a comprehensive method for synthesizing biochar-loaded nanofibers and reports useful characterization information that could inform future research to optimize nanofiber composition for particular environmental applications.
