Abstract

Responsive nanomaterials have emerged as key components in materials sciences. Herein, we report the one-step preparation of multi-stimuli responsive polyamine-salt aggregates (PSA) by ionically crosslinking polyethylenimine with potassium ferrioxalate (FeOx). The unique properties of FeOx enables a novel class of soft nanomaterial that disassembles by exposure to light, reducing environments and temperature.

摘要

响应性纳米材料已成为材料科学的关键组成部分。在此，我们报告了通过离子交联聚乙烯亚胺与铁氧酸钾（FeOx）一步制备多刺激响应聚胺盐聚集体（PSA）。FeOx 的独特性质使这种新型软纳米材料能够通过暴露于光、还原环境和温度来分解。
