Özet
This study presents a comprehensive review on biochar-filled polymer composites as a sustainable material. Biochar has emerged as one of the most promising reinforcement fillers in polymer matrices owing to its high surface area, thermal stability, and renewability. In addition, it enhances the mechanical properties of polymer matrices, including tensile strength, stiffness, and impact resistance. The study examined 450 articles published over the past decade, from November 2013 to November 2025, using data from Scopus and VOSviewer software to investigate global trends in research and international collaborations. It was followed by a critical review of various synthesis methods for biochars and their subsequent effects on composite properties, including mechanical, thermal, water-absorption, and biodegradability. Several studies have reported that incorporating 5-10 wt.% biochar can substantially improve the tensile strength, Young's modulus, hardness, impact strength, thermal properties, and crystallinity of polymers. Furthermore, it enhances several other properties, while influencing water absorption behavior and biodegradability depending on composition. The challenges and prospects for biochar-filled polymer composites are also discussed in depth. The study concludes that economic and ecological benefits will render the biochar-filled polymer composite an important material for developing eco-friendly construction materials, biomaterials, wastewater treatment, energy storage, CO2 capture, and soil remediation.
