摘要

在2418466号文章中，叶慧健、徐立新等人提出了一种带有共轭双键的超支化聚合物接枝，通过与自由基的加成反应产生捕获效应，从而延迟击穿初期电树的形成。抑制传导损耗和保持固有击穿的结合，使得聚醚酰亚胺纳米复合材料具有优异的高温能量密度和效率。

Ultrahigh Energy Storage Capability in Polyetherimide-Based Polymer Dielectrics Through Trapping Free Radicals Strategy (Adv. Funct. Mater. 14/2025)

Polymer Dielectrics

In article number 2418466, Huijian Ye, Lixin Xu, and co-workers present a hyperbranched polymer grafting with a conjugated double bond serves as a trapping effect through addition reaction with free radicals, which delays the formation of electrical treeing at initial stage of breakdown. The combination of suppressed conduction loss and maintaining intrinsic breakdown contributes to the outstanding high-temperature energy density and efficiency in the polyetherimide nanocomposite.
