论文摘要
菌丝结合的复合材料是可持续包装，隔热，时尚和建筑的有前途的材料。但是，成型是迄今为止探索的主要制造过程，强烈限制了设计可以扩大应用范围的复杂形状的能力。挤出是一种尚未探索具有设计自由和结构特性的菌丝结合的复合材料的便利和低能量成本的过程。在这项研究中，我们结合了廉价，易于使用的农业废料，竹制微生物，壳聚糖和来自Ganoderma lucidum的菌丝体，以建立一种可行，可挤出且可建造的复合混合物。我们研究竹纤维尺寸，壳聚糖浓度，pH和壳聚糖的重量比的影响，以确定菌丝体的最佳生长条件以及最高的机械刚度。因此，所产生的材料具有低能成本，可持续性，可以轻松以各种形式形成。开发的成分有望进一步探索使用农业废物的结构性应用的使用。
Mycelium-bound composites are promising materials for sustainable packaging, insulation, fashion, and architecture. However, moulding is the main fabrication process explored to date, strongly limiting the ability to design the complex shapes that could widen the range of applications. Extrusion is a facile and low energy-cost process that has not been explored yet for mycelium-bound composites with design freedom and structural properties. In this study, we combine cheap, easily and commonly available agricultural waste materials, bamboo microfibres, chitosan, and mycelium from Ganoderma Lucidum, to establish a composite mixture that is workable, extrudable and buildable. We study the impact of bamboo fibre size, chitosan concentration, pH and weight ratio of bamboo to chitosan to determine the optimum growth condition for the mycelium as well as highest mechanical stiffness. The resulting materials have thus low energy costs, are sustainable and can be shaped in diverse forms easily. The developed composition is promising to further explore the use of mycelium-bound materials for structural applications using agricultural waste.
