Title: SYNTHESIS OF POLYETHYLENE/CARBON NANOCOMPOSITES USING NI(II) COMPLEXES SUPPORTED ON CARBON CHEMICALLY MODIFIED WITH LEWIS ACIDS
Abstract:
The present invention relates to a method that allows the synthesis of oxidised and reduced polymer/carbon nanocomposites, the polymer being an olefin, more particularly polyethylene, the nanocomposites being obtained via in-situ polymerisation, the oxidised and reduced carbon being uniformly distributed in the polymer matrix. In the present invention, unless otherwise indicated, an oxidised and reduced carbon is considered to mean an oxidised carbon, the reduction of same being carried out in a controlled manner, obtaining predetermined percentages of reduction, for example, an oxidised and reduced carbon can be reduced by 27% or by 12%. In a first aspect, the present invention considers nickel complexes formed by α-diimine, β-cetoimine and α-iminocarboxamide ligands having a basic functionality in the structure thereof such as the CO and CN group.
