  • Corrosion and dissolution protection of a conductive silver/polymer composite
    Patent number: 6174606
    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.
