| 目的 通过木薯渣与聚琥珀酸丁二酯的复合，以期制备可降解的并保持优良力学性能的木薯渣/聚琥珀酸丁二酯复合材料，促进木薯渣的回收再利用，替代传统塑料制品。方法 采用生物质材料木薯渣，与聚琥珀酸丁二酯制备生物复合材料。通过傅里叶红外光谱仪、力学性能检测、扫描电镜和热重分析仪，分别研究所添加的生物质材料的粒径及添加量对复合材料的表观结构、微观结构、力学性能等的影响。结果 10 MPa热压压力下所制备复合材料的拉伸及弯曲强度达到峰值，分别为16.96，32.53 MPa，相比于4 MPa热压压力，材料的拉伸强度和弯曲强度分别提高了69.77%，148.7%。结论 在适宜的加工条件下加入一定量木薯渣，并不影响材料的综合性能，且能大幅提高木薯渣/聚琥珀酸丁二酯的降解性能。实现了农业废弃资源的回收再利用，提高了农作物附加价值，降低了复合材料的生产成本，并能促进生物质可降解复合材料的产业化，在可生物降解包装领域具有广阔的发展前景。 |

| The work aims to prepare biodegradable cassava residues and PBS composites by compounding cassava residues and PBS to promote the recycling and reusing properties of cassava residues and replace plastics with cassava residues/PBS composites. Cassava residues and PBS were used to prepare the biodegradable composites. The effects of particle size and amount of biomass materials on the apparent structure, microstructure and mechanical properties of the composites were respectively studied by Fourier transform infrared spectroscopy, mechanical property detection, scanning electron microscopy and thermogravimetric analysis. The tensile strength and bending strength of the composites prepared under the hot pressing pressure of 10 MPa reached the peak of 16.96 MPa and 32.53 MPa respectively. Compared with the values under the hot pressing pressure of 4 MPa, the tensile strength and bending strength of the composites were increased by 69.77% and 148.7% respectively. Certain amount of cassava residues will not affect the comprehensive properties of materials under appropriate conditions, but can greatly improve the biodegradability of cassava residues/PBS composites. Therefore, cassava residues/PBS composite realizes the recycling of agricultural waste resources, improves the added value of crops, reduces the production cost of composite materials, and promotes the industrialization of biodegradable composite materials, which has broad development prospects in the field of biodegradable packaging. |
