摘要

聚乳酸(PLA)/生物质聚合物复合长丝是具有天然材料特性的环保型3D打印耗材。以纤维素含量为46.2%的黄酒为原料,用NaOH溶液溶解淀粉和蛋白质,制备了富含纤维素的黄酒酒糟填料。然后,通过熔融共混和挤出工艺制备了含3-9 wt% CHG填料的PLA复合长丝。细丝截面的SEM图像显示CHG在复合材料中有良好的分散。XRD分析表明,纯PLA长丝的结晶度为22.2%,而含6 wt% CHG的PLA/CHG复合长丝的结晶度为70.0%。这种增强归因于聚乳酸结晶过程中CHG作为成核剂的作用。然后,使用3D打印机制作PLA/CHG复合材料试件。结果表明,3D打印PLA/CHG复合材料的抗拉强度为37.9 ~ 47.3 MPa,与PLA样品保持相当水平。此外,还对3D打印PLA/CHG复合材料在真实土壤环境下的生物降解性能进行了测试。在土壤中埋藏49天后,CHG含量为9 wt%的3D打印复合材料的质量损失率为0.6%,而3D打印PLA的质量损失率仅为0.1%,因为酒糟提供了微生物降解聚乳酸所需的碳氮源等必需营养物质。图形抽象

Improved crystallinity and biodegradability of 3D printable polylactic acid composite filaments filled with cellulose-enriched Huangjiu (Chinese rice wine) distillers’ grains as sustainable nucleating agents

Polylactic acid (PLA)/biomass polymer composite filaments are environmentally friendly 3D printing supplies with the features of natural materials. This study prepared cellulose-enriched Huangjiu (Chinese rice wine) distillers’ grains (CHG) fillers with 46.2 wt% cellulose by dissolving starch and protein with NaOH solution. Then, PLA composite filaments containing 3–9 wt% CHG fillers were prepared through melt blending and extrusion process. The SEM images of the cross-section of the filaments showed a good dispersion of CHG in composites. XRD analysis revealed that the crystallinity of pure PLA filaments was 22.2%, whereas that of the PLA/CHG composite filaments with 6 wt% CHG reached 70.0%. This enhancement is attributed to CHG acting as a nucleating agent during the crystallization process of PLA. After that, PLA/CHG composite test specimens were fabricated using a 3D printer. It was found that the tensile strengths of 3D printed PLA/CHG composites were 37.9–47.3 MPa, which were maintained at a comparable level to that of PLA sample. Furthermore, the biodegradation of 3D printed PLA/CHG composites were tested in real soil environment. After being buried in soil for 49 days, the mass loss rate was 0.6% for the 3D printed composite with 9 wt% CHG, while this value of the 3D printed PLA was only 0.1%, as distiller’s grains provide essential nutrients such as carbon and nitrogen source required for the microbial degradation of polylactic acid.

期刊介绍: Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
