摘要

生物塑料是化石燃料塑料的替代品，因为生物塑料是碳中性的，通常可以生物降解，从而有可能解决塑料污染和气候变化问题。其中，聚乳酸是传统石化聚合物的替代品。在此，我们回顾了聚乳酸的生产，重点是表面改性和生物活性化合物的整合。表面改性可通过化学处理、光接枝、表面夹层、等离子处理和涂层进行。生物活性化合物可通过封装、浸渍、熔融混合、溶剂浇注、电纺丝和原位聚合等方法加入。此外，还讨论了生物医学和包装应用。

Production methods and applications of bioactive polylactic acid: a review

Bioplastics appear as an alternative to fossil fuel-derived plastics because bioplastics are carbon neutral and often biodegradable, thus potentially solving the issues of plastic pollution and climate change. In particular, polylactic acid is a substitute for traditional petrochemical-based polymers. Here, we review polylactic acid production with focus on surface modification and integration of bioactive compounds. Surface can be modified by chemical treatment, photografting, surface entrapment, plasma treatment, and coating. Bioactive compounds can be incorporated by encapsulation, impregnation, melt blending, solvent casting, electrospinning, and in situ polymerization. Biomedical and packaging applications are discussed.

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
