Structure and properties of metal-free conductive tracks on polyethylene/multiwalled carbon nanotube composites as obtained by laser stimulated percolation

The investigation has been developed from basic characterization up to industrial scale manufacturing. The method is fast, flexible and innovative, because: (i) highly adherent tracks of any selected pattern on a low cost material can be obtained, (ii) the tracks are metal-free, a fact rendering the composite fully recyclable and (iii) the irradiated materials have application for electrical signals transport; (iv) the tracks are also characterized by piezoresistive properties so allowing their employment as pressure sensors.
