Flexible printed circuit board
First Claim
Patent Images
1. A flexible printed circuit board (PCB) comprising:
- a first polymer substrate having at least one of flexibility, stretchability, and elasticity;
a second polymer substrate having at least one of flexibility, stretchability, and elasticity;
a conductive track comprising metal nanowires disposed between the first polymer substrate and the second polymer substrate; and
a cured silane coupling agent configured to bond the conductive track to at least one of the first polymer substrate and the second polymer substrate,wherein the metal nanowires comprise at least one of silver (Ag), gold (Au), copper (Cu), platinum (Pt), palladium (Pd), nickel (Ni), cobalt (Co), and an alloy thereof, andwherein the metal nanowires are in contact with each other, thereby maintaining an electrically conductive network along an entirety of the conductive track, andwherein the first polymer substrate and the second polymer substrate each comprise at least one of a polyamide-based resin, polyester-based resin, a polyethylene-based resin, a polypropylene-based resin, and a polycarbonate-based resin.

Abstract
A flexible printed circuit board (PCB) has stretchability and durability. The flexible PCB includes: a first polymer substrate having flexibility, stretchability, or elasticity; a second polymer substrate having flexibility, stretchability, or elasticity; a conductive track disposed between the first and second polymer substrates and including metal nanowires; and a cured silane coupling agent which bonds the conductive track to at least one of the first and second polymer substrates.
