Synthesizing silver Nano-wires

In news

A team of Indian scientists and research students have developed a process for large-scale manufacturing of nano-materials (Silver nanowires) that can bring down the costs to less than one-tenth of the market price.

Details
  • Synthesis of one-dimensional nanomaterials like nanowires, nanotubes, and so on in large quantities is a technologically challenging task and hence makes it an expensive material.
  • Secondly, it is necessary to get uniform nanowire diameter range with a narrow variation in the length as it helps achieve uniform coating for touch screens or other conducting coating applications.
  • It is an economical process of continuous flow manufacturing of functional nano-materials (silver nanowires) at a large scale with support from the Advanced Manufacturing Technologies Program of the Department of Science & Technology, Government of India..
  • The product manufactured consists of silver nanowires possessing excellent conductivity, which can be used in making conducting inks and coatings for display technologies and flexible electronics.
  • A total of 5 national and international patents have also been filed for the novel process.
Significance
  • This is the first-ever continuous process for synthesizing a functional nanomaterial (Silver nanowires) efficiently with excellent product quality (aspect ratio of nanowires >1000) and at a very low cost (~20$/gm) on a large scale (500 g/day) with a footprint of the pilot plant not more than 6 sq. meters.
  • The process is a simple, cost-effective, and scalable synthesis route when compared to existing batch manufacturing protocols that even generate a large amount of nanoparticles in suspension, which is not easy to separate from nanowires.
  • This technology can make the Indian industries enter into the niche area of electronic chemicals and eventually open up new jobs.
