Method for establishing an anisotropic electrically conductive and optionally thermally conductive layer, comprising: providing a polymer composition, wherein the providing the polymer composition comprises the steps of: providing a non-conductive matrix of a flowable polymer composition having inherent photocurability, adding to said matrix conductive particles selected from the group consisting of metal particles, metal coated particles, metal oxide particles and carbon particles and any combination thereof, having an aspect ratio less than 20 in an amount sufficiently low to allow the concentration of the conductive particles to be maintained at a level lower than the percolation threshold of isotropic mixture and within the range 0.1-10 vol-%, adding the conductive particles as a predominantly non-aqueous dispersion, and placing the thus formed polymer composition in a receptacle in which exposure to UV light is prevented; applying a layer of the polymer composition to a substrate; characterised by applying an electric field across the polymer composition in a direction determined by the direction of intended electric conductivity, to thereby align the conductive particles into assemblies to form anisotropic electric pathways, and allowing the composition to cure under influence by UV light to provide a film and to preserve the electric conductive pathways. providing a polymer composition, wherein the providing the polymer composition comprises the steps of: providing a non-conductive matrix of a flowable polymer composition having inherent photocurability, adding to said matrix conductive particles selected from the group consisting of metal particles, metal coated particles, metal oxide particles and carbon particles and any combination thereof, having an aspect ratio less than 20 in an amount sufficiently low to allow the concentration of the conductive particles to be maintained at a level lower than the percolation threshold of isotropic mixture and within the range 0.1-10 vol-%, adding the conductive particles as a predominantly non-aqueous dispersion, and placing the thus formed polymer composition in a receptacle in which exposure to UV light is prevented; providing a non-conductive matrix of a flowable polymer composition having inherent photocurability, adding to said matrix conductive particles selected from the group consisting of metal particles, metal coated particles, metal oxide particles and carbon particles and any combination thereof, having an aspect ratio less than 20 in an amount sufficiently low to allow the concentration of the conductive particles to be maintained at a level lower than the percolation threshold of isotropic mixture and within the range 0.1-10 vol-%, adding the conductive particles as a predominantly non-aqueous dispersion, and placing the thus formed polymer composition in a receptacle in which exposure to UV light is prevented; applying a layer of the polymer composition to a substrate; characterised by applying an electric field across the polymer composition in a direction determined by the direction of intended electric conductivity, to thereby align the conductive particles into assemblies to form anisotropic electric pathways, and allowing the composition to cure under influence by UV light to provide a film and to preserve the electric conductive pathways.
