Developement of advanced wound dressings that possess antimicrobial properties for wound surface and absorbed exudate is challenging study and it facilitate effective wound healing. The polyurethane (PU) foam is one of the widely used moisture dressing that has superior ability to absorb exudate from wounds. In this study, we fabricated biomass-based antimicrobial PU foams containing silver nanoparticles and activated carbon. The mechanical property, moisture absorption speed, absorptivity, morphology and cell viability of the composite foam were characterized. Biomass-based antimicrobial carbon composites PU foam dressings showed significantly effective wound healing compared to controls.
