This work involved the preparation of a series of poly(ethylene 2,5-furandicarboxylate)/poly(glycolic acid)/polycaprolactone (PEF/PGA/PCL, referred to as PEF/PGACL) blends and the analysis of their miscibility, mechanical and optical properties, and biodegradability. It was found that the PEF/PGACL blend exhibits good miscibility with respect to the PGA component. Due to the presence of interfacial interaction and toughness PCL components within the PEF/PGACL blend, the tensile must overcome strong interfacial interaction originating from intermolecular interactions, which leads to the PEF/PGACL blend simultaneously maintaining balanced mechanical strength and toughness. The PEF/PGACL blend was, moreover, characterized by high optical transparency and a transmittance of more than ∼65% at a wavelength of 555 nm. In addition, the PEF/PGACL blend exhibited a bulk degradation mechanism, and sponge pores were formed on the surface and inside of the material due to preferential degradation of the PGA component, which was conducive to the further degradation of the internal component.

同时具有良好的热力学相容性和形态，可在生物 PEF/PGA/PCL 混合物中实现物理性能和生物降解性的平衡

本工作涉及一系列聚(2,5-呋喃二甲酸乙二醇酯)/聚(乙醇酸)/聚己内酯(PEF/PGA/PCL，简称PEF/PGACL)共混物的制备，并分析其混溶性、机械性能和性能。光学特性和生物降解性。结果发现，PEF/PGACL 共混物与 PGA 组分表现出良好的混溶性。由于PEF/PGACL共混物中存在界面相互作用和韧性PCL组分，拉伸必须克服源自分子间相互作用的强界面相互作用，这导致PEF/PGACL共混物同时保持平衡的机械强度和韧性。此外，PEF/PGACL 共混物还具有高光学透明度和在 555 nm 波长下透射率超过 65% 的特点。此外，PEF/PGACL共混物表现出本体降解机制，由于PGA组分的优先降解，在材料表面和内部形成海绵孔，有利于内部组分的进一步降解。
