摘要

开发可生物降解的光转换膜在农业和环境领域具有重要意义。本研究以可生物降解的聚乳酸(PLA)和聚己二酸丁烯-对苯二甲酸酯(PBAT)与不同量的铕(III)配合物(0.1%、0.3%和0.5%)通过溶液浇铸法制备了两种类型的光转换膜。铕(III)配合物均匀分布在PLA/PBAT中,随着铕(III)配合物的加入,膜的亲水性提高。该薄膜透光率高达80%,具有优异的光转换能力,可将紫外-可见光转换为红光。同时,PLA/PBAT/0.5%铕(III)复合膜的拉伸强度和断裂伸长率分别达到41.05 MPa和19.29%。这项工作为可降解光转换膜的研究提供了新的思路。

Synthesis of light conversion films through biodegradable polylactide/poly(butylene adipate-co-terephthalate) combined with europium(iii) complexes†

Developing biodegradable light conversion films is of great significance in the agriculture and environment fields. In this work, two types of light conversion films were successfully prepared using biodegradable polylactide (PLA) and poly (butylene adipate-co-terephthalate) (PBAT) combined with different amounts of europium(III) complexes (0.1%,0.3%, and 0.5%) through solution casting. Europium(III) complexes were dispersed uniformly in PLA/PBAT, the hydrophilicity of the films increased with the addition of europium(III) complexes. The films with a light transmittance of up to 80% displayed excellent light conversion capabilities and could convert UV-vis light into red light. Meanwhile, the tensile strength and elongation at the break of the PLA/PBAT/0.5% europium(III) complex film reached 41.05 MPa and 19.29%, respectively. This work provides new ideas for research on degradable light conversion films.
