Silver nanocomposites (Ag NCs) were prepared by two methods, chemical and physical synthesis using sodium borohydride gamma irradiation as a reducing tool. A one-step silver/kaolinite nanocomposite (Ag/Kln method has been developed successfully technique at room temperature under ambient pressure. The Ag/Kln NCs produced the ?-irradiation is pure without residues, good distribution with enhance...

in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...

The use of silver-based antimicrobial materials has been growing recently. Considering the threat developing silver-resistant bacteria, it is essential to address endurance such and amount silver released into environment. Here we report on a durable, antibacterial Ag/TiBx nanocomposite coating prepared by conventional magnetron sputtering. consists fine Ag clusters embedded in extremely hard, ...

the effect of ethanol-water media on the synthesis of ag/tio2 nanocomposite was investigated with 0.05, 0.1 and 0.5 (wt.%) of ag content. ethanol was used as hole-scavenger enhancing the photodecomposition of ag+ ions under illumination of near-uv light. the nanocomposites were further calcined to 300˚c and 400˚c under controlled atmosphere. the synthesized nanocomposites were tested for photoc...

Abstract Antibiotic nanocomposite polymers show great promise in treating a variety of pathogens that cause widespread disease. Sodium alginate-grafted diphenylamine (NaAlg-g-DPA) embedded with different ratios silver nanoparticles (AgNPs) was fabricated and characterized through techniques including FTIR, XRD, SEM for investigating the antimicrobial activity. XRD confirmed crystallinity these ...

Food packaging is defined as a co-ordinated system of preparing food for transport, distribution, storage, retailing, and end-use to satisfy the ultimate consumer with optimal cost (Coles et al., 2003). Food packaging is an essential part of modern society; commercially processed food could not be handled and distributed safely and efficiently without packaging. The World Packaging Organization...

In this study, the reinforcement effect of different proportions of eggshell/silver (ES-Ag) nanomaterial on the structural and antimicrobial properties of 70/30 poly(butylene-co-adipate terephthalate)/polylactic acid (PBAT/PLA) immiscible blends was investigated. The ES-Ag was synthesized using a single step ball milling process and characterized with X-ray diffraction (XRD), X-ray photoelectro...

Active packaging has played a significant role in consumers’ health and green environment over the years. Synthetic polymers, such as poly(ethylene terephthalate) (PET), polyethylene (PE), polypropylene (PP), polystyrene, poly(vinyl chloride) (PVC), polycarbonate (PC), poly(lactic acid) (PLA), etc., naturally derived ones, cellulose, starch, chitosan, are extensively used materials due to their...

Spoilage of food is a worldwide concern because poor faulty packaging material. Today the evolution nanotechnology in industry provides several benefits preservation, processing, and packaging. Nano has found many applications industry. such as oxygen (O2) scavengers, moisture antimicrobial, gas barrier properties, strength, flexibility, keeping an eye on freshness, etc. These nanomaterials hel...
