By suspending tiny metal nanoparticles in a liquid, Duke University scientists are developing conductive "ink" for inkjet printers to print cheap, customizable circuit patterns on almost any surface.
Printed electronics has been widely used on some devices, such as anti-theft radio frequency identification (RFID) tags, which can usually be found behind new DVDs. It currently has a major disadvantage: in order for this circuit to work, it must first be It is heated to melt all the nanoparticles into a single conductive wire, which makes it impossible to print circuits on cheap plastic or paper.
A new study done by researchers at Duke University shows that adjusting the shape of nanoparticles in ink can eliminate the need for heating.
By comparing the electrical conductivity of thin films made of silver nanostructures of different shapes, the researchers found that thin films made of electrons through silver nanowires are much easier than thin films made from other shapes such as nanospheres or microdisks. In fact, it is so easy for electrons to flow through thin films made of nanowires, so that they can be used in printed circuits without melting them together.
Benjamin Wiley, an assistant professor in the Department of Chemistry at Duke University, said: "The nanowires are 4000 times more conductive than the commonly used silver nanoparticles found on printed antennas for RFID tags. So if you use nanowires, then you do n’t need to print The circuit is heated to such a high temperature that you can use cheaper plastic or paper. "
