Abstract
Reaction of a carbonated soybean oil (CSBO) with a multifunctional amine curing agent containing both primary and secondary amine groups led to the formation of a non-isocyanate polyurethane network (NPU) with free secondary amine groups chemically anchored to the polymer network. The resulting NPU shaped as free standing membrane was immersed into a solution containing silver salt. Silver nanoparticles (AgNPs) were simply prepared and loaded into dressing membrane through a redox reaction between silver ions and free amine groups. Evaluation of the physical, mechanical and biological properties for this nanocomposite showed its high utility for using as an antimicrobial wound dressing for low exuding wounds.
