Tunable Broadband Clusteroluminescence in Hydroxylated Maleic Anhydride Copolymers via Hydrogen-Bond Network Regulation

Ruitao Pan, Weida Zhu, Ting Li, Xuhui Zhang et autres

Abstract Nonconjugated clusteroluminescent polymers provide a promising route to photofunctional materials without relying on extended π-conjugated structures. However, achieving efficient, long-wavelength emission remains a challenge. Herein, hydroxyethyl methacrylate (HEMA) was introduced into a maleic anhydride/vinyl acetate copolymer backbone to design hydroxylated maleic …

High-Performance Polylactide Vitrimers via Polyol-Assisted Network Engineering through Reactive Blending

Yichen Liu, Qiang Xu, Le Jin, Lijun Song et autres

Abstract Polylactide (PLA) is a promising biobased and biodegradable polymer, but its limited heat resistance and mechanical performance hinder broader engineering applications. Herein, high-strength and reprocessable PLA vitrimers were prepared through a facile reactive blending strategy. A multifunctional polyol, bis(2-hydroxyethyl)imino-tris(hydroxymethyl)methane (BTM), was …
