Developing eco-friendly products to replace fossil-based ones which are difficult to degrade and pollute survival environment, is of great significance for human health and environmental protection. Here, the preparation of green polyvinyl alcohol/polylactic acid (PVA/PLA) materials has been achieved for the first time using a simple and effective strategy. Interestingly, after the composite of PVA with PLA, PLA can remarkedly enhance tensile strength, elongation at break, biocompatibility and thermostability of the PVA/PLA material. Moreover, the material is biodegradable in natural environment. At the same time, scanning electron micrograph (SEM), X-ray diffraction (XRD) and infrared spectra (IR) techniques are employed to systematically study the effects of PVA/PLA mass ratio on the morphology, crystallinity and chemical structure of the PVA/PLA material and possible interaction between PVA and PLA. It is expected that this study can provide a new insight into the fabrication of green PVA-based products with high performance and practical application.

高性能聚乙烯醇/聚乳酸材料：易于制备和改进的性能

开发环保产品来替代难以降解、污染生存环境的化石产品，对人类健康和环境保护具有重要意义。在这里，使用简单有效的策略首次实现了绿色聚乙烯醇/聚乳酸（PVA/PLA）材料的制备。有趣的是，PVA与PLA复合后，PLA可以显着提高PVA/PLA材料的拉伸强度、断裂伸长率、生物相容性和热稳定性。此外，该材料在自然环境中可生物降解。同时，采用扫描电镜（SEM）、X射线衍射（XRD）和红外光谱（IR）等技术，系统地研究了PVA/PLA质量比对形貌的影响，PVA/PLA材料的结晶度和化学结构以及PVA和PLA之间可能的相互作用。预计这项研究可以为制造具有高性能和实际应用的绿色 PVA 基产品提供新的见解。
