产品说明

一般描述

  • 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 platics 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 H particles have an average thickness of approximately 15 nanometers and a typical surface area of 50 to 80 m2/g. Grade H is available with average particle diameters of 5, 15 or 25 microns.
  • Note: Graphene nanoplatelets have naturally occurring functional groups like ethers, carboxyls, or hydroxyls that can react with atmospheric humidity to form acids or other compounds. These functional groups are present on the edges of the particles and their wt% varies with particle size.
