Hierarchical Design of Microalgae Biocomposites for Multifunctionality

As the need for sustainable, high-performance materials grows, creating eco-friendly alternatives to traditional composites has become increasingly critical. Renewable biomaterials, including bioplastics and natural fibers, offer a promising pathway toward sustainability. However, their incorporation in composites typically necessitates high-energy processing and harsh chemical treatments to achieve adequate interfacial adhesion. In this talk, I will present an additive manufacturing approach to fabricate microalgae-based biocomposites at ambient temperature, eliminating the need for petrochemical additives. This method produces lightweight structures with hierarchical architectures and complex geometries, demonstrating mechanical properties and thermal insulation comparable to conventional polymers and wood.
