Preparation of Mycelium-poplar Particle Porous Composites with Thermal Insulation and Fire-retardant Performance
The extensive use of petroleum-based high-molecular-polymer porous materials has led to severe plastic pollution,commonly known as"white pollution".In this study,we developed a green and sustainable mycelium-poplar particle porous composite material by inoculating and cultivating fungal mycelium on poplar particles.After the mycelium grew through the poplar particles,the porous composite material was prepared by air-drying directly.The results indicated that the porous composite material had a low density(0.165 g·cm-3),high porosity(82.7％),and hydrophobic surface(contact angle:131.8°).The composite material exhibited excellent mechanical properties(compression strength of 2.39 MPa;Young's modulus of 9.79 MPa).Additionally,the porous composite material had a low thermal conductivity(0.066 W/mK)and an outstanding limited oxygen index(28.4％).This research demonstrates a simple and eco-friendly method for the preparation of mycelium-poplar particle porous composite materials,which holds significant reference value for the high-value utilization of agricultural and forestry biomass.
