Advantages
High evaporation efficiency of 86%
MX/HK@CuS-3 thin sheets achieve a photothermal evaporation efficiency of 86%, significantly outperforming conventional materials.
99.9% bacterial inactivation in 20 min
Under NIR and simulated sunlight illumination, over 99.9% of E. coli and S. aureus are inactivated within 20 min.
Triple antibacterial mechanism
The combination of Cu2+ release, photothermal and photodynamic effects effectively eradicates biofilms and reduces bacterial adhesion.
Good blood compatibility
The MX/HK@CuS series show impressive blood compatibility, indicating biocompatibility and environmental safety.
Applications
- Solar water evaporation：Provides antibacterial surfaces for solar evaporators, preventing biofouling and maintaining evaporation efficiency.
- Photothermal evaporation materials：Serves as a high-efficiency photothermal conversion material to enhance solar-to-steam conversion.
- Antimicrobial coatings：Coating surfaces to rapidly kill bacteria and eradicate biofilms, reducing infection risk.
- MOF composite antimicrobial materials：Exploits synergistic MOF-CuS effects for controlled ion release and photodynamic antimicrobial action.
