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