Washington, Jan 9 (IANS) For those who love soaking in smell of paper while reading their favourite book, here comes a breaking news. Scientists in China are in the process of developing a metal ink - made of small sheets of copper - that can be used to write a functioning, flexible electric circuit on regular printer paper, said a study published in the journal ACS Applied Materials and Interfaces. The conductive ink could pave the way for a wide range of new bendable gadgets - such as electronic books that look, feel and smell like traditional paperbacks - said the study that appeared in the journal Applied Materials & Interfaces.

Washington, Jan 9 (IANS) For those who love soaking in smell of paper while reading their favourite book, here comes a breaking news.

Scientists in China are in the process of developing a metal ink - made of small sheets of copper - that can be used to write a functioning, flexible electric circuit on regular printer paper, said a study published in the journal ACS Applied Materials and Interfaces.

The conductive ink could pave the way for a wide range of new bendable gadgets - such as electronic books that look, feel and smell like traditional paperbacks - said the study that appeared in the journal Applied Materials & Interfaces.

To have a versatile conductive ink, researchers tried copper nanosheets, which are inexpensive and highly conductive.

They made copper nanosheets coated with silver nanoparticles in the lab and incorporated this material into an ink pen, using it to draw patterns of lines, words and even flowers on regular printer paper.

To show that the ink could conduct electricity, the scientists studded the drawings with small LED lights that lit up when the circuit was connected to a battery.

To test the ink's flexibility, they folded the papers 1,000 times, even crumpling them up, and showed that the ink maintained 80 to 90 percent of its conductivity, added the research funding by the National Natural Science Foundation of China.
