Iran-Made Conductive Ink with Copper Nanoparticles Low-Cost Alternative to Silver-Based Ink
“Our technology is designed based on a fast electrolysis operation. In this method, instead of using electric current for traditional electrolysis, acidic bases are used, which allows copper nanoparticles to be deposited on oxide surfaces. Prototypes of the product have been able to sit on iron pellets and other oxide surfaces,” Omid Pourgaleh Dari, the managing director of the company, told ANA on the sidelines of the 16th International Nanotechnology Exhibition in Tehran.
He explained that the company’s main goal was to produce conductive ink for printing printed circuits on plastic, paper, and traditional fibers, adding, “They have achieved initial success in this field, but the challenge that has not yet been overcome is the rapid oxidation of the surface of the copper nanoparticles and we are working on this problem.”
“The silver ink available in the market is very expensive, given the global price of silver, while the production of copper ink by us is much less expensive,” Pourgaleh Dari said.
The 16th International Nano Technology Exhibition and the First Exhibition of Advanced Technologies of Iran was inaugurated at the Tehran International Fairground.
Held from November 2 to 5, the Nano Exhibition featured over 150 innovative companies showcasing advancements in nanotechnology. Meanwhile, the Exhibition of Advanced Technologies hosted 80 knowledge-based and technological products, attracting visitors, particularly students, researchers, and investors.
