摘要

This study presents a biomimetic strategy for efficiently synthesizing polylevodopa (poly(

-DOPA)) nanoparticles using benzoyl peroxide

yielding materials with tailored electronic structures and significantly enhanced UV-shielding performance for advanced protective coatings.

Abstract

We report a bioinspired

facile strategy for synthesizing melanin-like nanoparticles

via

highly selective room-temperature polymerization of levodopa (

-DOPA)

a native eumelanin precursor

using benzoyl peroxide. This method overcomes traditional synthesis limitations

yielding poly(

-DOPA) with covalently incorporated benzoyl fragments

and demonstrates significantly enhanced ultraviolet absorption for advanced photoprotective applications.
