Abstract:
A method for forming a body comprising a mixture of a matrix and conductive particles, whereby the conductive particles are formed into aligned conductive pathways in an alignment step by applying an electric field between alignment electrodes and thereafter stabilizing the mixture wherein the conductive particles have a low aspect ratio; and a polymeric composition and method for producing such composition which is curable by UV light to an anisotropic electrically conductive polymer layer, comprising i) providing a non-conductive matrix of a flowable polymer composition having inherent photocurability, ii) adding to matrix conductive particles having low aspect ratio in an amount to allow the concentration of the conductive particles to be maintained at a level lower than the percolation threshold, and iii) placing the formed composition in a receptacle where exposure to UV light is prevented, and a method for establishing an anisotropic electrically conductive, optionally thermally conductive.
