Mussel-inspired polydopamine (PDA) coatings have gained significant attention in various fields, including biomedicine, energy, detection, and UV protection, owing to their versatile promising properties. Among these properties, shielding stands out as a key feature of PDA coatings. Nevertheless, the current methods for tuning UV-shielding properties are quite limited, only rely on thickness adjustment, which might involve additional issues like color visible light transmittance coating layer. In this study, we propose facile modular approach enhance absorption by incorporating thiol-heterocycle (TH) derivatives. Both pre- post-modification strategies can effectively impede formation conjugated structures within PDA, leading enhanced layers. More importantly, improve while reducing absorption. Furthermore, method enabled efficient regulation altering ring type (benzene or pyridine ring) substituent (methoxyl group hydrogen atom).
