RT journal article T1 Integrating Cork Biochar as a Green Filler via Photopolymerization A1 Romero Ocaña, Ismael A1 Fernández Delgado, Natalia A1 Benito Jareño, Javier A1 Molina Rubio, Sergio Ignacio A2 Ciencia de los Materiales e Ingeniería Metalúrgica y Química Inorgánica K1 3D printing K1 cork biochar K1 green filler K1 composite K1 vat photopolymerization AB This study analyzed the use of cork-derived biochar, obtained through pyrolysis, as a more sustainable additive than traditional carbon materials. In addition, the present study explored its application in a polymer matrix through additive manufacturing via stereolithography. To the best of our knowledge, this approach has not been reported in scientific literature. The cork biochar retained the morphology of the original cork and integrated well into the photocurable polymer, as demonstrated by scanning electron microscopy. This integration can contribute to the formation of internal networks within the material, potentially modifying some of its properties. At specific low percentages, cork biochar enhanced both the electrical conductivity and mechanical properties of photocurable polymers. Notably, the required biochar concentrations were minimal, facilitating its incorporation into the photopolymer matrix. Additionally, the thermal stability of the material slightly improved at certain percentages but remained comparable to that of the original polymer in all cases. These findings highlight the potential of cork biochar as a sustainable additive for advanced polymer composites.
