We have designed printable, biocompatible, and degradable ion gels by combining a novel ABA triblock aliphatic polyester, poly(ε-decalactone)-b-poly(dl-lactide)-b-poly(ε-decalactone), and a low toxicity ionic liquid, 1-butyl-1-methylpyrrolidinium bistrifluoromethanesulfonylimide ([P14][TFSI]). Due to the favorable compatibility between amorphous poly(dl-lactide) and [P14][TFSI] and the insolubility of the poly(ε-decalactone), the triblock polymer forms self-assembled micellar cross-links similar to thermoplastic elastomers, which ensures similar processing conditions and mechanical robustness during the fabrication of printed electrolyte-gated organic transistor devices. Additionally, the ester backbone in the polymer structure enables efficient hydrolytic degradation of these ion gels compared to those made previously using carbon-backbone polymers.

由可再生 ABA 三嵌段聚酯和低毒性离子液体制成的可打印、可降解和生物相容性离子凝胶

我们通过结合新型 ABA 三嵌段脂肪族聚酯、聚(ε-癸内酯)-b-聚(dl-丙交酯)-b-聚(ε-癸内酯)和低毒性离子液体,1-丁基-1-甲基吡咯烷鎓双三氟甲磺酰亚胺([P 14 ][TFSI])。由于无定形聚(dl-丙交酯)和 [P 14][TFSI] 和聚 (ε-癸内酯) 的不溶性,三嵌段聚合物形成类似于热塑性弹性体的自组装胶束交联,确保在印刷电解质门控有机晶体管的制造过程中具有相似的加工条件和机械稳定性设备。此外,与以前使用碳骨架聚合物制成的那些相比,聚合物结构中的酯骨架使这些离子凝胶能够有效地水解降解。
