Researchers from Imperial College London, Durham University, University of Cambridge, The Chinese University of Hong Kong, Zhejiang University, Beihang University, Nanjing Tech University, Macquarie University, University of British Columbia and Aalto University have collaborated to examine the "coffee ring effect" which has been hindering the industrial deployment of functional inks with graphene, 2D materials, and nanoparticles because it makes printed electronic devices behave irregularly.
The team of researchers has now created a new family of inks that overcomes this problem, enabling the fabrication of new electronics such as sensors, light detectors, batteries and solar cells.
