Abstract:
The discovery of unique heat conduction properties of graphene [1] motivated research focused on thermal conductivity of graphene, few-layer graphene and composites with graphene fillers [2]. Recent developments suggest that the large-scale practical applications of graphene can be expected specifically in thermal management – thermal interface materials, thermal coatings and related [3-4]. From the other side, it has been demonstrated that graphene composites are efficient electromagnetic (EM) interference shielding materials – they can reflect and absorb EM energy efficiently even at low loading fraction of graphene, below the percolation limit, while remaining electrically insulating [5]. The dual function of graphene composites, and the possibility of independent control of their electrical and thermal properties provides extra benefits for practical applications. The general class of the van der Waals (vdW) layered materials is not limited to two-dimensional (2D) materials such as graphene or transition metal dichalcogenides (TMDs), which exfoliate into atomic planes. There exist vdW materials with one-dimensional (1D) motif in their crystal structure, such as transition metal trichalcogenides (TMT), which exfoliate into needle-like atomic chains [6-7]. The exceptional current conduction and EM interaction properties of such materials will also be discussed both in terms of fundamental science and practical applications.
