​Tailored electrical conductivity of nanocomposites containing graphite nanoplatelets

The project is directed towards properties of nanocomposites containing graphene particles. An aim is to take advantage of the favorable electrical conductivity of graphene-based materials.
 


A number of applications involve control of the electrical conductivity and in the case of polymeric components graphene is an interesting additive. Our studies concern nanocomposites based on polyolefins and graphene-based particles.
 
Since the project is carried out in a scale close to industrial practice, significant amounts of graphene-based additives are required. At present it is the necessary to base the studies on graphite nanoplatelets (GNP), i. e. consisting of number of graphene layers. The processing method used for the manufacturing is extrusion, which is a conventional melt processing technique for plastics. The challenge is, by using, different kinds of flow fields, exfoliate these platelets and then achieve an aimed electrical conductivity at low contents of the additive (low percolation threshold). Hybrid composites based on graphene and other carbon structures are also examined.
