Iranians createantibacterial nanocoating

Amirkabir University of Technology's researchers have produced an antibacterial nanosilver coating on the surface of polyethylene films.

Abdolhamid Sadeqnejad, Abdolreza Aroujalian, Ahmad Reza Raisi and Sharhzad Fazel, faculty members of the university, were researchers of the project.

The coating can be used in packaging food such as milk to prevent bacterial growth, increase shelf-life and maintain the quality and taste of foods.  

Sadeqnejad said results of this research will also have applications in medical, pharmaceutical and textile industries.

He explained that the coating helps produce clothes made from the antimicrobial yarns and prevent algal growth.

The expert noted that in this research, the surface of polyethylene film was treated by the corona discharge and then the modified polymeric film was immersed in a solution of silver nanoparticles synthesized by chemical reduction of silver salt
