Abstract
The present disclosure relates to conductors comprising a conducting member comprising silver and a functionalized organosiloxane network having at least one functional group capable of trapping silver or a silver ion as well as to methods of preparing the same. For example, the functionalized organosiloxane network can at least substantially inhibit dendrite formation between a first conducting member and a second conducting member. For example, the conductors may be used in an electronic circuit such as a printed electronic circuit.

- and
- a functionalized organosiloxane network coating the at least two conducting members, the functionalized organosiloxane network being obtained by reacting at least one organosiloxane network precursor of Formula (I) or at least one organosiloxane network prepared by the condensation of at least one organosiloxane network precursor of Formula (I):
- wherein
- R1, R2 and R3 are each independently chosen from hydroxy and a group that is hydrolysable under conditions to form a hydroxylated organosilane;
- and
- L1 has the formula:
- wherein
- Y is chosen from C1-10alkylene, C2-10alkenylene, C2-10alkynylene, C6-14arylene and —C1-6alkylene-C6-14arylene-C1-6alkylene;
- and
- R4 is chosen from H, C1-6alkyl, C2-6alkenyl, C2-6alkynyl and C6-10aryl, with at least one functionalization precursor of Formula (II):
- L2—X (II),
- wherein
- X is chosen from a carboxylic acid, a thiol and a sulfonate;
- and
- L2 has the formula:
- wherein A is absent or is chosen from C1-20alkylene, C2-20alkenylene, C2-20alkynylene, C6-14arylene and C1-10alkylene-C6-14arylene- C1-10alkylene—,
- under conditions to form the functionalized organosiloxane network;
- and
- wherein the functionalized organosiloxane network at least substantially inhibits dendrite formation between a first conducting member and a second conducting member.
