In the framework of the public-private laboratory TRIPODE, ENEA has designed and realized a prototype of a machinery system for treatment and synthesis of ceramic powders starting from solid and gaseous matrix based on plasma torch technology, integrating competences in material science , mechanics, environmental technologies of recovery and reuse. Moreover a recovery and reutilization process of valuable materials (chip and antenna) has been developed from TAG RFIDs at their end of life. Demonstrative TAG has been realised using recovered chip and carbon fibre antennas.
The application of nanomaterials is more and more increasing in a wide range of products with high technology content and is acquiring a potential importance even increasing in environmental issues. In this context, nanotechnology-based products, belonging to organic electronic sectors of new generation, realized also with printing techniques and manufactured even on flexible polymeric layers, play a primary role.
Organic matrices generally belong to these categories: 50-200 micron polymeric papers (PET or PEN) containing nanoparticles to improve the “barrier” properties; film in metal oxide or nanotubes in composite with a polymeric matrix for anode materials; multilayer film with an alternate ceramic/polymer deposition; additive polymer conjugated with semiconductors nanoparticles, conductive inks made of Ag, Au, Cu nanoparticles.
Regarding the potential scientific interest, the prototype of the thermal plasma might be used in different research fields in which are needed to study production processes of sub-micronic and nanometric materials. These issues are of interest not only for ENEA but also for various other research entities, both Italians and foreigners. Regarding the potential industrial interest, the machinery system represents a forefront technology that allows testing processes on little productive lots for application in the field of structural composite, electronic and catalytic systems. Recovery process of s from RFIDs, vice versa, put the emphasis on recycle, reuse and recovery of these valuable materials contained in the new consumer electronic and therefore at an emerging market of primary and secondary matters.
