Abstract
A conductive composite is described containing silver particles and a polymer which covers each silver particle and wherein a heterocyclic organic compound containing nitrogen such as benzotriazole (BTA) is present to reduce Ag dissolution and ion mobility by forming a water insoluble complex with the Ag ion. The invention overcomes the problem of silver dissolution or corrosion a conductive composite as a result of normal high Ag ion mobility in the presence of moisture and an electric field.
