Study Notes
Robust Myco-Composites: A Biocomposite Platform for Versatile Hybrid-Living Materials
- Abstract: Fungal mycelium, a network of filamentous threads, thrives on lignocellulosic waste. It exhibits rapid growth, hydrophobicity, and intrinsic regeneration, effectively creating next-generation sustainable and functional composites (myco-composites). Existing myco-composites are limited by conventional mold-based manufacturing processes. A novel platform is introduced that uses high-resolution biocomposite additive manufacturing and indirect inoculation for robust and scalable mycelium colonization. These myco-composites show improved properties, such as tensile strength (up to 160 MPa), compared to existing materials.
Biocomposite Design
-
Composition: The composite is designed using minimally processed, non-toxic, and biodegradable materials from waste streams. Chitosan and cellulose are used as the basic materials, offering mechanical properties and abundance in natural structures. Spent coffee grounds are incorporated for sustainable nutritional support of fungal growth.
-
Mechanical properties: The fully infilled 3D-printed composite demonstrates increased Young's modulus compared to cast samples in tension (up to 340 MPa). However, compressive modulus for printed material was lower than cast material due to mechanical defects in the printing.
-
Indirect inoculation: This method of fungal growth was found more effective and robust on 3D-printed structures, filling voids efficiently and displaying high biocompatibility with multiple fungi.
Impacts of Mycelium Colonization
-
Mechanical Properties: Colonization significantly enhances mechanical properties compared to uncolonized composites, including over a fifteen-fold increase in modulus.
-
Wettability and Absorption: Full colonization improved hydrophobicity (increased contact angle). Water absorption, measured after 24 hours, was substantially lower in colonized composites.
Bio-welded Containers and Textiles
- Versatile applications: The platform enables the creation of foldable bio-welded containers and flexible textile-like structures. This showcases versatility in structural and textile applications. Mycelium's ability to bridge gaps offers potential for sustainable packaging.
