    Sciences
  • The University of Exeter

2
Outline
  • Types of graphene based composites
  • Useful properties of graphene in composites
  • Potential applications of various types of
    graphhene composites

3
Graphene Based Composites (1)
  • Polymer-Graphene Composites
  • Metal-Graphene Composites
  • Ceramic-Graphene Composites

4
Graphene Based Composites (2)
  • Coating/Film/Paper Form
  • Sandwich Form
  • Bulk form

5
Useful Properties of Graphene in Composites
  • Functional (e.g., Electrical) properties
  • Thermal properties
  • Mechanical properties
  • Lightweight, unique morphology, chemical
    stability.

  • Potential applications Electronic circuit
    boards, heat sink and light weight high
    performance thermal management systems.

11
Graphene Reinforced Composites
  • Mechanical properties
  • 1) Stiffest (E gt 1 Tpa),
  • 2) Strength gt100-GPa tensile strength (40 times
    gt steel).
  • Morphology 2D shape
  • ? Ideal reinforcement phases to make stronger
    and tougher composites for various applications
