Nanocomposites based on polyethylene oxide and silver nanoparticles (AgNPs) were developed as new active antimicrobial and antibiofilm coatings. Silver colloids were synthesized by nanosecond-pulsed laser ablation synthesis in solution using an organic solvent to ensure a long-term stability of nanocolloids and a good solubility in polymeric solution. AgNPs were incorporated in a biodegradable polymer matrix for the preparation of composite films. The coatings’ surface chemical composition (assessed by X-ray photoelectron spectroscopy) was correlated with the ion release.

Abstract
Nanocomposites based on polyethylene oxide and silver nanoparticles (AgNPs) were developed as new active antimicrobial and antibiofilm coatings. Silver colloids were synthesized by nanosecond-pulsed laser ablation synthesis in solution using an organic solvent to ensure a long-term stability of nanocolloids and a good solubility in polymeric solution. AgNPs were incorporated in a biodegradable polymer matrix for the preparation of composite films. The coatings’ surface chemical composition (assessed by X-ray photoelectron spectroscopy) was correlated with the ion release.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
