Metallic layers added by plasma on polyethylene

This work presents a study of the addition of layers composed by different metals on thin films of low-density polyethylene (PE) in order to combine the properties of both components. The process involves the immersion of PE in ionic atmospheres of O, N, Fe, Cr, Ni, and Ti to form layers and agglomerates on the surface of the polymer. As this process requires a great exchange of energy, many experimental conditions were studied in order to preserve the structural integrity of the organic compounds. The results indicate that the surface of PE eroded and reacted with the particular reactivity of the plasma gases in the first step, and after that, the metallic particles were adhered forming thin layers. The combination of N and O in different proportions in the plasma produced in PE combinations of fibered and parallel-tracked morphologies that influenced in the polymer–metal interface.
