Graphite (C) Nanopowder Main Feature
Graphite nanopowder, consisting of ultrafine particles of graphite, inherits the core characteristics of graphite but exhibits unique features due to its nanoscale dimensions.The nanoscale size of graphite particles significantly increases the surface area to volume ratio. This high surface area is beneficial for applications requiring high reactivity or adsorption capacity, such as in catalysis, energy storage.Graphite is a good conductor of electricity due to the delocalized π electrons in its structure. The nanopowder form can offer even greater electrical conductivity per unit mass compared to bulk graphite, making it ideal for use in conductive films, coatings, and composites.Graphite is chemically inert and resistant to many chemicals. Its nanopowder form retains this property, making it suitable for use in chemical sensors, corrosion-resistant coatings, and as a support material for catalysts.
