METHOD FOR PRODUCING THERMALLY CONDUCTIVE SHEET AND THERMALLY CONDUCTIVE SHEET PRODUCED BY THE METHOD

摘要

Provided is a method for producing a thermally conductive sheet, comprising shaping a thermally conductive precursor composition into a sheet, the thermally conductive precursor composition comprising a (meth)acrylic monomer or a polymerizable oligomer thereof, a photopolymerization initiator, and a thermally conductive filler present in an amount of 20 vol % or more based on the total volume of the thermally conductive composition obtained, and irradiating the front surface and the back surface of the sheet with ultraviolet radiation at different ultraviolet irradiation intensities, thereby curing the sheet and obtaining a thermally conductive sheet having a single-layer thermally conductive composition and having tackiness differing between the front surface and the back surface.
