Studies from Indian Institute of Science Update Current Data on General Science (In situ formation of silver nanowire networks on paper)

September 12, 2014

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Science. According to news reporting from Bangalore, India, by NewsRx journalists, research stated, "Simple, universally adaptable techniques for fabricating conductive patterns are required to translate laboratory-scale innovations into low-cost solutions for the developing world. Silver nanostructures have emerged as attractive candidates for forming such conductive patterns."

The news correspondents obtained a quote from the research from the Indian Institute of Science, "We report here the in situ formation of conductive silver-nanowire networks on paper, thereby eliminating the need for either cost-intensive ink formulation or substrate preparation or complex post-deposition sintering steps. Reminiscent of the photographic process of 'salt printing', a desktop office printer was used to deposit desired patterns of silver bromide on paper, which were subsequently exposed to light and then immersed in a photographic developer. Percolating silver nanowire networks that conformally coated the paper fibres were formed after 10 min of exposure to light from a commercial halogen lamp."

According to the news reporters, the research concluded: "Thus, conductive and patterned films with sheet resistances of the order of 4 Omega/rectangle can be easily formed by combining two widely used processes - inkjet printing and photographic development."
