The incorporation of TiO2 nanoparticles into (ethylene-vinyl alcohol)-based food packaging copolymers affords an opportunity to synthesize polymer-based nanocomposite materials with novel and powerful biocidal and photodegradability properties, resulting in the production of an advanced, environmentally friendly system prepared using a cost-effective synthesis method via a simple melt compounding without the need of a coupling agent incorporation. The presented materials display an unprecedented performance in the killing of both Gram positive and negative bacteria without the necessity of being release to the media and an easy degradation under sunlight which favorably competes with biodegradation procedures.
将二氧化钛纳米颗粒掺入基于乙烯-乙烯醇的食品包装共聚物中,为合成具有新型强效杀菌和光降解性能的聚合物基纳米复合材料提供了契机,从而制备出一种先进的、环境友好型体系,该体系采用经济高效的合成方法,通过简单的熔融共混制备而成,无需添加偶联剂。所展示的材料在杀灭革兰氏阳性和阴性细菌方面表现出前所未有的性能,无需释放到介质中,并且在阳光下易于降解,这与生物降解过程相比具有优势。
