Title:
METHOD FOR FORMING UV-CURABLE CONDUCTIVE COMPOSITIONS AND A COMPOSITION THUS FORMED
Document Type and Number:
WIPO Patent Application WO/2012/081992
Kind Code:
A3
Abstract:
Polymeric, optionally adhesive, composition and method for producing such composition with the ability to be subsequently cured by UV light to an anisotropic electrically conductive polymer layer, comprising the steps of i) providing a non-conductive matrix of a flowable polymer composition having inherent photocurability, ii) adding to said matrix conductive particles having a low aspect ratio in an amount sufficiently low to allow the concentration of the conductive particles to be maintained at a level lower than the percolation threshold, and iii) placing the thus formed composition in a receptacle in which exposure to UV light is prevented. A method for establishing an anisotropic electrically conductive and optionally thermally conductive layer is also disclosed.
