The aim of this paper is to investigate the characteristics of thermoplastic sugar palm starch/agar (TPSA) blend containing Eucheuma cottonii seaweed waste as biofiller. The composites were prepared by melt-mixing and hot pressing at 140°C for 10min. The TPSA/seaweed composites were characterized for their mechanical, thermal and biodegradation properties. Incorporation of seaweed from 0 to 40wt.% has significantly improved the tensile, flexural, and impact properties of the TPSA/seaweed composites. Scanning electron micrograph of the tensile fracture showed homogeneous surface with formation of cleavage plane. It is also evident from TGA results that thermal stability of the composites were enhanced with addition of seaweed. After soil burial for 2 and 4 weeks, the biodegradation of the composites was enhanced with addition of seaweed. Overall, the incorporation of seaweed into TPSA enhances the properties of TPSA for short-life product application such as tray, plate, etc.
本文旨在研究以麒麟菜海藻废料作为生物填料的热塑性糖棕淀粉/琼脂（TPSA）共混物的特性。通过在140°C下熔融混合和热压10分钟制备复合材料。对TPSA/海藻复合材料的机械性能、热性能和生物降解性能进行了表征。加入0至40wt.%的海藻显著提高了TPSA/海藻复合材料的拉伸、弯曲和冲击性能。拉伸断裂的扫描电子显微镜照片显示表面均匀且形成了解理面。从热重分析结果也可以明显看出，加入海藻后复合材料的热稳定性得到了提高。在土壤中掩埋2周和4周后，加入海藻增强了复合材料的生物降解性。总体而言，将海藻加入TPSA中可增强TPSA的性能，适用于托盘、盘子等短寿命产品应用。
