Abstract:
Following the principles of green chemistry, Iranian researchers at Amirkabir University of Technology managed to concurrently synthesize silver nanoparticles and the coating over woolen fibers, achieving a relatively high durability.

Scientists Synthesize Durable Silver Nanoparticles Entrapped in Woolen Fibers

Tehran, Iran | Posted on April 25th, 2012

"Bearing the basic concepts of the green chemistry in the mind, we have managed to synthesize the nanoparticles both in the aqueous phase and over a woolen medium. We employed Lecithin to serve as the stabilizer and carrier of the silver nanoparticles through the woolen medium," Hossein Barani, a member of the research group, told INIC.

The goals targeted by this research project apparently include the synthesis of silver nanoparticles with the help of Lecithin as a biodegradable surface active agent, to apply environmentally friendly chemicals in the synthesis of nanoparticles, simultaneous synthesis and loading of the nanoparticles into the fiber structures which effectively improves the quality and durability of the washing.

"Lecithin acts as a stabilizer for the silver nanoparticles during their synthesis step and also is the vehicle by which the nanoparticles are transferred into the woolen fiber structures. The prepared silver nanoparticles possess approximate dimensions of 7 nm and are entrapped inside a liposomic vesicle," Barani added.

"Simultaneous synthesis and loading of the silver nanoparticles is in favor of the loading efficiency and durability of washing. In addition, the presence of Lecithin boosts the loading quality, avoids excessive concentration of the nanoparticles upon the fibers' surfaces, reduces the undesired yellowing of the fabric, and increases the antibacterial performance through a gradual release with lowest toxicity for fibroblast cells," he reiterated.

Barani also evaluated the commercialization of the method as promising, and said, "In case of industrial investment, the proposed approach can be implemented to the production line of textile companies with practical ease."

A more technical report detailing the mentioned research work has recently been published in the Molecular Membrane Biology, volume 28, pages 206-215, 2011.
