Novel Polymer Ink Exhibits High Stability in Air and at High Temperatures Written by AZoMApr 22 2021 At Linköping University, Sweden, scientists have designed a stable, highly conductive polymer ink. The breakthrough opens the door for novel printed electronics with high energy efficiency. The ink can be deposited by simply spraying the solution onto a surface, making organic electronic devices easier and cheaper to manufacture. Image Credit: Thor Balkhed. The study findings have been published in the Nature Communications journal. Electrically conducting polymers have enabled the growth of lightweight and flexible electronic components like batteries, transistors, light-emitting diodes, solar cells, and organic biosensors.
