Title:
CONDUCTING WIRE COMPOSITION FOR DIRECT SCANNING-TYPE PRODUCTION AND FLEXIBLE CIRCUIT PRODUCED USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/239049
Kind Code:
A1
Abstract:
A conducting wire composition for the direct scanning-type production of a flexible circuit according to the present invention has the advantage of being applicable to a direct scanning method in additive manufacturing in that a highly flexible and optimal epoxy cured body can be produced by adjusting the content of an epoxy resin and a curing agent and the viscosity of an epoxy mixture is optimized by selecting a volatile and non-reactive optimal diluent and adjusting the content thereof. In addition, the conducting wire composition for the direct scanning-type production of a flexible circuit has the advantage that the deterioration of electrical properties caused by residues does not occur because the diluent is completely volatilized and disappears, and has the advantage of not only having low resistivity and excellent electrical conductivity properties because a maximum content of silver flakes, which are electrically conductive materials, are homogeneously dispersed in an epoxy polymer, but also showing an insignificant change in electrical conductivity without breaking even when bent at the maximum curvature.
