Claims31
A method of producing a metal/conductive polymer composite colloid, said method comprising:
- combining:
- (i) a pre-formed metal colloid comprising a noble metal colloid;
- and
- (ii) a water-soluble conductive polymer;
- under conditions sufficient for said water-soluble conductive polymer to adsorb to metal particles of said pre-formed metal colloid to produce a metal/conductive polymer composite colloid.

A method of producing a metal/conductive polymer composite colloid, said method comprising:
- combining:
- (i) a first volume of a pre-formed metal colloid comprising noble metal particles suspended in an aqueous medium;
- and
- (ii) a second volume of a solution of a water-soluble conductive polymer;
- under conditions sufficient for said water-soluble conductive polymer to adsorb to metal particles of said pre-formed metal colloid to produce a metal/conductive polymer composite colloid;
- wherein said second volume has a water-soluble conductive polymer concentration that provides for substantially no free water-soluble polymer in said metal/conductive polymer composite colloid.
