TEHRAN (INIC) -- Iranian researchers from Islamic Azad University, Yazd Branch, successfully used graphene nanosheets to design and fabricate electroconductive fibers in which the amount of conductivity can be adjusted.

The obtained textiles have the ability to be used in the fabrication of electronic, smart, electromagnetic-resistant, waterproof, and multipurpose fibers.

"The purpose of this research was to study the feasibility of the use of graphene nanosheets in creating conductive coatings on the surface of textiles. The effect of various parameters on the conductivity of the cloth was studied as well. The effect of graphene on color change, mechanical properties, and the passage of light through the textiles was investigated too," Mohammad Shatteri Khalilabadi, one of the researchers, explained about the research.

Results showed significant effect of the type of reducer on the conductivity of the textile coated with graphene and also on the adjustment of the textile conductivity as the concentration of graphene oxide solution or the number of coatings change. Microscopic study on the samples demonstrates the coating of the textile with a very thin layer of graphene, which had negligible effect on the surface morphology of the textile. The coated graphene layer has a very high washing and mechanical strength although it has negligible effect on the reduction of mechanical properties of the textile.

Graphene can be a good choice for replacement with other conductive materials such as conductive polymers, indium tin oxide, gold nanocoatings, and carbon nanotubes that have problems, including the lack of homogenous coating, high fragility, high price, lack of desirable adsorption and low stability. The obtained textiles can also be used in the production of flexible electronic pieces such as sensors, capacitors, electrodes, solar cells, and so forth.

About INIC

Iran has recognized the significance of nanotechnology like other pioneering countries and started its activities in line with development of the technology. In this regard and as first step, a Study Committee for Nanotechnology in Iran began its activities in 2001 and finally Iran Nanotechnology Initiative Council (INIC) was established in the country in 2003. The INIC is tasked with determining the general policies for the development of nanotechnology in the country and pursuing the case with implementation of the policies.

Iran's success in achieving a proper place among 15 countries which are advanced in nanotechnology and making attempt to promote the position in a bid to develop Iran's economy are the main missions of the INIC. Iran Nanotechnology Initiative Council is seeking to pave the ground for activity of the private sector and production of wealth within the society through adopting outlook, providing facilities, creating market and removing the existing problems.
