Descrição geral

Graphite dispersion is an acceptor molecule with high thermal and electrical conductivity. It can be used in the formation of an electrode for electrochemical applications.

Aplicação

Graphite dispersion (few-layers: 3-15 graphene layers, 1.0mg/mL in acetone-water) can be used for a variety application such as
  • in the synthesis of graphene layer
  • in the preparation of ruthenium catalyst for the synthesis of ammonia
  • development of biosensors
  • fabrication of multi-layer thin films for li-ion micro-batteries

Nota de preparo

Production method: Thermomechanical exfoliation of natural graphite in a liquid medium controlled at a nanoscale level.
