摘要
通过熔融共混的方式制备了聚乳酸(PLA)/聚丁二酸丁二醇酯(PBS)/山茶籽粉(CSP)(ASP)3D打印线材,并采用FDM技术打印成ASP骨架用于吸附亚甲基蓝(MB)。ASP骨架对MB的吸附平衡时间为72 h,此时吸附率为89.89%。吸附过程遵循伪二级动力学模型,且可以用Langmuir等温吸附模型进行描述,是一个自发的放热过程。将农业废弃物与生物基3D打印材料结合,实现了农业废弃物的增值化利用,降低了生物基3D打印材料的成本,并实现了功能化应用。
3D-printed filament of Polylactic acid(PLA)/poly(butylene succinate)(PBS)/Camellia seed powder(CSP)(ASP)was prepared by melting blends.The filament was then used for printing ASP scaffold via fused deposition modeling(FDM)for adsorbing methylene blue(MB).The equilibrium time of the adsorption is 72 h,and 89.89%removal ratio is obtained.Pseudo-second-order model is more suitable to describe the adsorption process,and which follows the Langmuir isotherm.The adsorption is determined to be an exothermic,spontaneous process.The combination of 3D printing and agricultural wastes is a good way to realize the valuation of agricultural wastes and the reduction of the cost of 3D printing material.Furthermore,the functional application of 3D printing is also achieved.
