| Abstract Scope |
When using these organic materials in engineering applications, there can be a sacrifice in the mechanical or material properties as compared to traditional engineered materials. The creation of hybrid organic-inorganic materials may allow for the use of natural materials in applications that would otherwise not be feasible. We created fungal-silica hybrid materials using various methods of biotemplating, an advanced manufacturing method that can copy natural structures or reinforce them with inorganic materials. The soaking time in an acidic catalyst and the aging time were varied to test changes in properties. Structural, chemical, and mechanical characterization was performed, and showed that a longer soaking time resulted in denser structures with greater mechanical resistance. A longer aging time similarly resulted in greater mechanical resistance. Theoretical predictive models were made to correlate soaking time to mechanical behavior, which may help in the design and manufacturing of silica-reinforced fungal materials. |
