A method for making electrically conductive patterns using a metal particle-free ink containing a catalyst precursor that subsequently forms catalytic seed nanoparticles in-situ during or after a patterning step. The catalytic pattern is fixed on the target substrate after which catalytic sites are generated by reduction of the precursor to metallic particles. The reductant is selected to minimize particle generation under ambient conditions but the reduction of the catalyst precursors in the ink may be accelerated by an external input such as heat or ultraviolet energy. This catalytic pattern is then metallized with electroless plating to generate a conductive metallic pattern corresponding to the first catalyst pattern.

Resumen de: US20260022258A1
Many non-conductive engineered materials, including organic or inorganic powders, fibers, films, foams and even bulk materials, are used as substrates and effectively coated with a thin layer of polypyrrole (PPy) by the so-called “in-situ polymerization” of pyrrole monomer. Subsequently, a layer of conductive copper sulfide (CuS) as a top coat is applied to the above PPy-coated substrates by the electroless plating so as to render them electrically conductive on their surfaces. It is critical and useful that PPy is able to facilitate the electroless plating of CuS on its surface with enhanced adhesion, which results in a CuS/PPy coating system having stable electrical conductivity even under the condition of a high temperature (up to ̃200° C.) for a prolonged time.
