Antifouling and rechargeable antibacterial polyurethane modified with N -halamine for dental unit waterlines

Key Points

• The aim is to assess the effectiveness of polyurethane modified with N-halamine for preventing biofilm formation in dental unit waterlines.
• Modified polyurethane surfaces incorporated rechargeable N-Cl bonds for enhanced antibacterial properties.
• Contact-killing and anti-adhesion properties evaluated on treated surfaces.
• Significant reduction in biofilm formation observed on N-halamine modified surfaces compared to untreated controls.
• Enhanced antibacterial efficacy maintained over multiple recharge cycles, implying sustained effectiveness.
