Iranian Academic Develops Ultrasonic Method for Extracting Nanofibers

In an interview with ANA, Hassan Heidari, expounded on applications of producing threads using the ultrasonic method.

The idea is that the nanofibers or polyester fibers that are produced in factories spray nanoparticles on the surface of the fiber.

With the passage of time and as a result of washing, these nanoparticles are separated from the fiber.

“We ionized polyester fibers or yarn with polyethylene terephthalate, activating the carboxylate of the chemical compound.”

In this method, nylon, polyester, and cotton threads are instead coated with a thin metallic mesh made up of a random network of silver nanowires.

This can lead to a lower material cost, lower weight, and thinner thread, as well as greater mechanical flexibility.

Heidari explained that by activating the carboxylate, the chemical composition is also activated, and in the next step, silver nanoparticles establish a permanent chemical bond with the activated carboxylate.

The thread that is produced using the ultrasonic method has the advantage of connecting nanoparticles permanently.

It does not disappear as a result of washing, and the antibacterial property of nanoparticles will remain constant.

Heidari made the remarks on the sidelines of the national Asreh Omid Event which was held in late May in Tehran’s Grand Mosalla with the participation of 3,000 knowledge-based companies, laboratories, research teams, and startups.

The expansion of nanotechnology export programs in recent years and the establishment of bases for exporting nanoproducts to China, India, Indonesia, Syria, Turkey, and Iraq have provided the opportunity for the entry of Iranian nanotechnology goods, equipment, and services into global markets.

Some 270 companies are active in the nanotechnology field and it is predicted that their revenue will reach up to 80 trillion rials (nearly $310 million), former Vice President for Science and Technology, Sourena Sattari, has said.

Currently, nanotech products are produced and marketed in more than 15 industrial fields based on domestic technologies and are being exported to 49 countries from five continents.
