摘要

储存二氧化碳并将其转化为有价值的物质对于应对气候变化至关重要。由二氧化碳和环氧丙烷共聚而成的聚碳酸丙烯酯(PPC)在商业应用中大有可为,但由于其固有特性的限制,其实际应用也受到了限制。此外,由于缺乏对 PPC 生物降解的系统研究,其使用后的处置也变得更加复杂。在本研究中,我们合成了各种聚合物,包括 PPC 均聚物、PPC/蓖麻油星型共聚物和 PPC/聚(l-乳酸)多嵌段共聚物(PPC-mb-PLLAs),不仅缓解了 PPC 的脆性,还系统地探索了它们的生物降解性。在评估聚合物的生物降解时,采用了天然土壤和工业堆肥条件。此外,元基因组分析确定了负责聚合物降解的微生物,为生物降解过程的机制提供了宝贵的见解。

Storing CO2 and converting it into valuable substances are crucial for addressing climate change. While poly(propylene carbonate) (PPC), formed through the copolymerization of CO2 and propylene oxide, holds promise in commercial applications, practical limitations arise due to inherent property constraints. Additionally, the lack of systematic research on PPC biodegradation complicates its post-use disposal. In this study, we synthesized various polymers, including PPC homopolymers, PPC/castor oil star copolymers, and PPC/poly(l-lactic acid) multiblock copolymers (PPC-mb-PLLAs), not only to mitigate the brittle properties of PPC but also to systematically explore their biodegradability. Both natural soil and industrial composting conditions were employed to assess the biodegradation of the polymers. Furthermore, metagenomic analysis identified the microorganisms responsible for polymer degradation, offering valuable insights into the mechanism of the biodegradation process.

期刊介绍: Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology.
