文摘

The incorporation of TiO₂ nanoparticles into (ethylene-vinyl alcohol)-based food packaging copolymers affords an opportunity to synthesizepolymer-based nanocomposite materials with novel and powerful biocidal and photodegradability properties, resulting in the production of anadvanced, environmentally friendly system prepared using a cost-effective synthesis method via a simple melt compounding without the needof a coupling agent incorporation. The presented materials display an unprecedented performance in the killing of both Gram positive andnegative bacteria without the necessity of being release to the media and an easy degradation under sunlight which favorably competes withbiodegradation procedures.
