Abstract

This research aimed to address the growing demand for sustainable construction materials by developing mycelium bio-composites as innovative, biobased insulation. Utilizing local agricultural lignocellulosic residual by-products bound by mycelium, they offer a promising circular alternative to fossil-based materials. This manuscript is a condensed view of the Mythic project, focused on optimizing growth techniques and material properties to ensure technical feasibility. In the growth optimization phase, a novel inoculation method using reclaimed cellulose, instead of grain kernel-based inoculants, significantly improved growth speed and substrate colonization, reducing incubation times and aligning with industrial production needs. Material property optimization focused on thermal properties, fire resistance, and moisture behavior -- key attributes for insulation materials. Mycelium bio-composites achieved thermal conductivity values of 0.034-0.039 W/m·K, comparable to conventional insulators. The moisture behaviour properties are considered to be sufficient for its use as insulation. Hydrophobic properties were enhanced through a coating, improving durability in humid conditions. These innovations ensure that mycelium bio-composites meet industry benchmarks for various applications.

油菜籽秸秆与灵芝菌丝体生物复合材料的制备及热湿性能测试

这项研究旨在通过开发菌丝生物复合材料作为创新的生物基绝缘材料来满足对可持续建筑材料日益增长的需求。利用当地农业木质纤维素残留副产品结合菌丝体，他们提供了一个有前途的循环替代化石基材料。这份手稿是Mythic项目的浓缩视图，重点是优化生长技术和材料性能，以确保技术可行性。在生长优化阶段，采用再生纤维素代替以籽粒为基础的接种剂，显著提高了生长速度和底物定殖，缩短了培养时间，符合工业生产需要。材料性能优化主要关注隔热材料的热性能、耐火性能和防潮性能——这些都是隔热材料的关键属性。菌丝生物复合材料的导热系数为0.034-0.039 W/m·K，与传统绝缘体相当。防潮性能被认为足以作为绝缘材料使用。通过涂层增强了疏水性，提高了在潮湿条件下的耐久性。这些创新确保菌丝体生物复合材料满足各种应用的行业基准。
