Claims23
A conductive composite comprising:
- (a) a polymer;
- (b) a conductor selected from metals and metal alloys having a melting temperature below about 60° C.;
- and
- (c) a thickening agent.
A composition comprising a metal or metal alloy having a melting temperature below 60° C. and an organic thickening agent.
An composition comprising
- (a) a polyol or a di- or polyisocyanate;
- (b) a conductor selected from metals and metal alloys having a melting temperature below 60° C.;
- and
- (c) a thickening agent.
A composition comprising a polyol and a metal or metal alloy having a melting temperature below 60° C.
A method for preparing a conductive composite comprising:
- combining an isocyanate composition comprising;
- (a) a di- or polyisocyanate;
- (b) a conductor selected from metals and metal alloys having a melting temperature below 60° C.;
- and
- (c) a thickening agent;
- with a polyol and/or a diamine to form a mixture;
- and
- allowing the mixture to cure to form the conductive composite.
A conductive composite comprising:
- an elastomer;
- a conductor selected from metals and metal alloys having a melting temperature below 60° C.;
- and
- a thickening agent,
- wherein the conductive composite exhibits a minimum sheet resistance of less than 100 Ohm/sq, an elongation greater than or equal to 50%, and a tensile strength greater than or equal to 3 MPa.
A conductive composite comprising a polymer and an electrically conductive network stably and homogeneously, continuously, or both homogenously and continuously entrapped within the polymer, the network comprising a conductor having a melting point below about 60° C. and a compound or metal that does not alloy with the conductor.
