摘要
将热塑性交联淀粉与聚己内酯熔融共混,制备了可生物降解材料,考察了各种条件对材料的影响。结果表明:增塑剂用量对材料的力学性能有明显的影响,拉伸强度下降、断裂伸长率上升;甘油与水相比,甘油对断裂伸长率的改善作用更明显;体系中增塑剂甘油含量的增加有助于提高材料的耐水性,但略微降低了材料的降解性能。
Thermosplastic crosslinked starch (TPCS) and polycaprolactone (PCL) are blended to prepare a biodegradable material. Results show that plasticizer has obvious effect on the mechanical performance of the materials: tensile strength is descended, and extension at break is raised; compared with water, glycerin can improve obviously extension at break; increasing plasticizer glycerin is helpful to enhance water resistance of the raw materials, but slightly decrease the degradation performance of the raw materials.
