摘要

Dynamic selenonium salts were strategically integrated into transparent polyurethane (PU) matrices

endowing the coatings with dual functionality: self-healing and antibacterial properties. Through systematically optimizing the selenonium salt concentration

the PU coatings achieved maximal antibacterial efficacy while retaining their intrinsic self-healing properties.

Abstract

In this study

dynamic selenonium salts were incorporated into a polyurethane (PU) matrix to develop transparent

healable and antibacterial coatings. Through systematic formulation optimization

optically clear materials with excellent room-temperature hardness were obtained. Fine-tuning the selenonium content established a synergy between antibacterial performance and network dynamics

as evidenced by vitrimer-like rheological behavior at elevated temperatures. Consequently

the coatings exhibited outstanding reprocessability while maintaining high transparency and structural stability after prolonged saltwater exposure. These integrated features underscore the potential of the developed cationic PU coatings as robust

multifunctional materials for electronic device protection and marine antifouling

combining long-term transparency

recyclability

and antibacterial durability.
