PCE175 Project


Project title: Nanocomposite materials obtained by laser techniques for flexible electronic devices
Periode: 2016

Contact Person:
Project Director: Dr. E. György (INFLPR)

Coordinator:
National Institute for Laser, Plasma and Radiation Physics - INFLPR
Atomiștilor 409, Măgurele, Romania


Objectives:
The main objective of the project is the development of conducting rGO-based materials using laser techniques. GO has several advantages, it can be produced using inexpensive graphite as raw material by cost-effective chemical methods with a high yield, and owing to its highly hydrophilic character is can form stable aqueous colloids. However, GO typically shows poor electrical conductivity which restricts its application fields. As a consequence, a key research topic is the development of new reduction techniques, to produce graphene-like materials, which partly reproduce the structure and electrical properties of graphene. In order to further enhance the electrical conductivity or rGO, the addition of other highly conductive nanomaterials, single and multiwall CNTs, and noble metal nanoparticles is foreseen in the frame of this project. The developed laser-based methods are versatile, eco-friendly and easy to be implemented in industrial processes.
