There is an urgent need to develop a series of multifunctional materials with good biocompatibility, high mechanical strength, hemostatic properties, antiadhesion, and anti-infection for applications in wound care. However, successfully developing challenging. In this study, two superhydrophobic composite coatings strong antifouling blood repellency, fast hemostasis, antibacterial activity are prepared on cotton fabric surface by simple, green, low-cost one-step dip-coating technology. The results discussed the manuscript reveals that can maintain stability, water durability under various types damage, high-temperature treatment, long-term light irradiation. also exhibit repellency solid pollutants, highly viscous liquid blood. vitro vivo experiments show both have anticlot adhesion properties. More importantly, coating prevents bacterial growth released Cu2+ Zn2+ ions chitosan achieve bactericidal thereby protecting injured skin from infection. enhance antifouling, hemostatic, functions blood-repellent dressings therefore broad application prospects medical textile fields.
