일반 설명

  • xGnP® graphene nanoplatelets are unique nanoparticles consisting of short stacks of graphene sheets having a platelet shape.
  • The unique size and platelet morphology of xGnP® graphene nanoplatelets makes these particles especially effective at providing barrier properties, while their pure graphitic composition makes them excellent electrical and thermal conductors. xGnP® graphene nanoplatelets can improve mechanical properties such as stiffness, strength, and surface hardness of the matrix material.
  • xGnP® graphene nanoplatelets are compatible with almost all polymers, and can be an active ingredient in inks or coatings as well as an excellent additive to plastics of all types. The unique manufacturing processes are non-oxidizing, so material has a pristine graphitic surface of sp2 carbon molecules that makes it especially suitable for applications requiring high electrical or thermal conductivity.
  • Grade C particles typically consist of aggregates of submicron platelets that have a particle diameter of less than 2 microns and a typical particle thickness of a few nanometers, depending on the surface area. In general, grade C shows very high surface area and macro-porosity. Grade C particles are available in different grades with average surface areas of 300, 500 and 750 m2/g.
