摘要

这项工作的目的是证明使用可回收的可生物降解材料作为减轻重量的细胞材料的可能性。对循环利用对聚乳酸(PLA)性能和泡沫性能的影响进行了实验研究。研究了循环利用对聚合物结晶度、热性能和粘弹性的影响。在批处理过程中，形成了聚乳酸和再生聚乳酸的胞状结构。与原始材料相比，观察到更高的结晶度，更低的粘度值和更低的熔融强度。对于回收PLA，获得了精细的细胞结构和低密度(0.60 g/cm3)。

Effect of Recycling on the Cellular Structure of Polylactide in a Batch Process

The aim of the work is to demonstrate the possibility of using recycled biodegradable material as a cellular material with a reduced weight. An experimental study on the influence of recycling on the properties and foam ability of polylactide (PLA) was carried out. The influence of recycling on the polymer crystallinity, thermal and viscoelastic properties was investigated. During the batch process the cellular structure in PLA and recycled PLA were created. A higher degree of crystallinity, a lower viscosity value and a lower melt strength for recycled PLA, as compared to original material, were observed. For the recycled PLA, a fine cellular structure and low density (0.60 g/cm3) were obtained.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
