Query: Effect of graphene and carbon-nitride nanofillers on the thermal
  transport properties of polymer nanocomposites: A combined molecular dynamics
  and finite element study   Low thermal conductivity of polymers, which is one of the considerable
drawbacks of commonly used composite structures, has been the focus of many
researchers aiming to achieve high-performance polymer-based nanocomposites
through the inclusion of highly thermally conductive fillers inside the polymer
matrices. Thus, in the present study, a multiscale scheme using non-equilibrium
molecular dynamics (NEMD) and finite element (FE) method is developed to
explore the impact of different nano-sized fillers (carbon-nitride and
graphene) on the effective thermal conductivity of polyethylene-based
nanocomposites. We show that the thermal conductivity of amorphous polyethylene
at room temperature using the reactive bond order (REBO) interatomic potential
is nearly 0.36 0.05W/mK. Also, the atomistic results predict that, compared to
the C3N and graphene nanosheets, the C2N nanofilm presents a much stronger
interfacial thermal conductance (ITC) with polyethylene. Furthermore, the
results indicate that the effective thermal conductivity values of
C2N-polyethylene, C3N-polyethylene, and graphene-polyethylene nanocomposite, at
constant volume fractions of 1%, are about 0.47, 0.56, and 0.74 W/mK,
respectively. In other words, the results of our models reveal that the thermal
conductivity of fillers is the dominant factor that defines the effective
thermal conductivity of nanocomposites.
