Scientists in Portugal create promissory material for new generation of devices
A team of researchers from the University of Coimbra (UC) developed a graphene coated liquid metal nanocompositewhich can be used as a transparent conductor, with applications in the next generation of electronic devices and panels.
In a study published in the journal Advanced Material TechnologiesLow cost technician of fast laser processing, scalable cost, which pYou can have large impactable screens, flexible in flexible areas and even biosensitive (wearable).

“Liquid metals are relevant because Economy and self-regeneration, in addition to excellent thermal dissipation. Therefore, it is an important step towards the application and development of very flexible and resistant screens», explains Mahmo Tavakoli, director of the “Soft and Printed Microelectronics” Laboratory at the Institute of Systems and Robotics (ISR) at the University of Coimbra (FCTUC).
The researchers believe that, in the future, these nanoparticles with special properties could be printed on large conductive surfaces at low cost.
“Graphene-encapsulated liquid metal particles are a promising new class of two-phase composite, with application in the next generation of electronic devices,” see Mahmoud Tavakoli, who handled the study. “We have demonstrated that it is possible to manufacture these new electrodes quickly – in a few seconds – at low cost and on a large scale”
This solution is first deposited onto the substitute via spray coating and then processed via a low-cost laser, adds o. This allows simultaneously reduce, reduce, and fine-tune high resolution of deposited films.
The composition of the new material and the fabric method presented in this study represents an important step towards the large-scale, low-cost production Large Electrodes Made of Graphene.
The next step of the investigation will be explore the use of other types of lasers for conductivity or transparency of electrodes, as well as studying the applications of this technique in the areas of fine electronics, gas sensors and improving films and energy storage devices.
The investigation, developed within the scope of the project Wowof the Carnegie Mellon Portugal Program, and of the MATIS-Sustainable Industrial Materials and Technologies project, through the Portugal 2020 Program, is the cover theme of the latest edition of the magazine Advanced Material Technologies.
