Discuss the three types of conductive materials: carbon-based, metallic, and composite.

Carbon-based Conductive Materials

Common carbon-based conductive materials include: conductive carbon black, graphite, carbon fiber, carbon nanotubes, and graphene, etc.

Carbon-based conductive materials feature excellent conductivity, coloring power, chemical stability, low density, and affordability. Their applications in conductive inks and adhesives are widespread across the electronics and chemical industries. However, they suffer from poor dispersion stability and dark colors, which limit their practical applications.

2. Metal-based conductive materials

Including silver, copper, and nickel series, which boast excellent conductivity and malleability, with relatively light colors, and a wide range of applications.

3. Composite Conductive Materials and Their Properties:

Metal-coated conductive fillers: Generally, a thin layer of anti-corrosive and chemically stable metal is coated onto the metal surface using surface treatment techniques, resulting in composite conductive materials with low resistance and excellent overall performance, metal-coated metal.

As follows:

Conductive rubber with silver-plated copper: Excellent electrical conductivity.

Nickel-plated Graphite Conductive Rubber: Features excellent conductivity, electromagnetic shielding properties, and corrosion resistance.

Nickel-plated copper conductive rubber: Offers excellent conductivity and electromagnetic shielding properties.
