Document Type and Number:
WIPO Patent Application WO/2018/159374
Kind Code:
A1
Abstract:
[Problem] To realize a flexible electrically conductive coating film that is inexpensive and has high durability, and to provide a wearable device using such coating film as wiring. [Solution] An electrically conductive paste is obtained by blending and kneading at least: an electrically conductive filler which comprises metal-coated particles having a non-surface-treated metal layer on the surface of electrically non-conductive core particles; a binder resin comprising an elastomer; and an organic solvent. By further adding an additive having a surface of free energy of 30 mJ/m2 or less, repetition durability is improved. An electrically conductive coating film obtained from the electrically conductive paste exhibits high durability to repeated expansion and contraction, is suitable for use in wearable applications requiring flexibility, and is inexpensive.
